Automating the process of jib crane design

Automating the process of jib crane design Automating the Process of Jib Crane Design Chapter 1 Introduction 1.1 Introduction In a jib crane horizontal jib is fixed to a piller or to a wall and supports a movable lift. Jib crane mostly used in industries and for military purpose. The jib can also swing by the arc which corresponds to lateral movement (additional). These types of crane are used in warehouse stores to lift the goods to all floors. In the materials handling industry workers are often required to do large payloads. In situations where large payload movements would require extra forces to be applied by the operator, the material handling devices are provided now with automatic or motorized power assists. These are basically designed such that they can reduce operator tiredness and damage. Such cranes are power assisted jib cranes with advanced design. A jib crane consists of a pendulum like end line attached to a rota-table jib. Within this general cranes category there exist some devices with multiple degrees of freedom which includes variable load line length and jib length which is also variable. Point-point payload maneuvers with jib cranes are performed so as not to incite the spherical pendulum modes of the cable attached and payload assembly. In a typical way these pendulum modes yet time-varying, but shows low frequencies. That results in slow performance; hence high construction and transportation costs can occur. The figure below shows the different parts of jib crane. [Franklin, 1994] Jib Cranes are industrial machines which mostly uses for materials movements in construction of buildings, production halls, assembly lines, storage areas, and power plants. The design features of jib crane vary widely according to their major operational and manufacturing specifications such as: crane structure according to motion, weight and type of the load, crane location, geometric features, and environmental conditions. However, a review of the available literature tells that technical design of jib cranes are highly saturated and standardized in many industrial companies and organizations independent of the jib crane type. [Marchese, 1974] 1.2 Problems/Issues Today most companies currently uses manual calculations to provide product design specification for their jib cranes for their customers requirements. This job involves very hard work and the manual calculation. The reduced man work will efficient the companys process for design and manufacturing of the product. So it would be beneficial to automate this process which requires a software package in which all calculation can be done automatic. 1.2.1 Current Problems The problems in jib crane design incorporate advance design for their different customers and their different purpose and the companies dont have a computer program which calculates the design specifications for manufacturing for their customers. [Erden, 1996] 1.2.2 Literature review Current material handling systems exhibit anisotropic behavior. Their two planar degrees of freedom have requirement of different force inputs from the operator. For jib crane in generation of isotropic behavior there can be two directions, the first direction generates isotropy by floating the boom above the load. The second direction adds a power trolley and is capable of assisting by providing power to actually accelerate the given load. We can provide a cable angle sensor and ultrasonic distance sensor for the intelligence necessary to achieve isotropy. [A, Lorenz, 1999] Consideration of the available technology that is mainly based on the accumulated previous experience is important for better performance, higher safety and more reliable designs. It is well known that generic features of jib crane components are similar for various different types of cranes. Since the jib crane design procedures are highly standardized with these components, main effort and time spent in jib crane design projects are mostly for interpretation and implementation of the available design. In the figure below a rotatory jib crane is shown with degrees of freedom. The crane considered here consists of a rotatable jib with a load line attached to the end. A mass, representing a payload, is attached to the end of the load-line. The figure (1) is shown for analysis. The three co-ordinate system (three vectors shown) attached to the jib and rotates about the hub with an angular rate (gamma). The rotation angles are defined as rotation of the load-line about the two axes. The attachment point of the load-line to the jib is at a distance x from the centre of rotation of hub. The load-line has length L and the payload mass m. Alternative Concepts: Several concepts were evaluated: Single tension rod A single-rod design is assumed during the initial calculations to determine reaction forces on the building column. Extra analysis explained that this design did not have enough power for its length and capacity. Truss A trussed beam is considered, as it would have provided a very light, strong crane. This design was shortly discarded because it would have proven very difficult to study and build. Two tension rods A two-rod design can be selected because it could be made strong enough to support the design load up to the length of 30 feet, yet be simple enough to analyze with a combination of manual calculations and computer-based analysis. 1.2.3 Objectives To understand design and analysis of jib crane To design jib crane in AutoCAD / Solid work To develop calculation of jib crane data using Microsoft excel Chapter 2 Methodology 2.1 Flow chart: Start Design and analysis for the jib crane (Existing Design) and a modified design AutoCAD Design Create Microsoft excel software End In the initial stage the project overview and scope of project is analyzed. Further on the literature based on the current design is reviewed. Next stage is examining the design advancement of the jib crane using sensors and control to automate the crane process and in lowering the operator stress and power. After that the software developed will be used in design and selection of major jib crane parts for the manufacturing. The design stated by software would be seen as in AutoCAD or solid work. In the final stage the further advancement and conclusion will be made. The stages of the project are shown below. 2.2 Description: The project will consist of manual calculations of design specifications for the complex structures like Jib crane along with automated process. The use of Microsoft software along with some other package will be usedso that it would be more users friendly. First thecalculationwill be donelike moment of inertia, torque and transmission ratios etc.for the advanced mechanicaldesign of the Jib crane[Juvinall,1991] then the number of variables will be included in software to give the product design specification for jib crane directly which will help in reducing the manwork. The simple advantage to get the all data which are required in jib crane design will come directly and this process will help in reducing time taken to produce a required jib crane. The work will be done with existing data and current methods of calculation. At the end of project, a manufacturer should not calculate the various design data for the custom design of the jib crane for different purpose. The jib crane software itself will pick the most essential and important data and according to that will choose the simplified method to give design specification directly. Reader will be able to understand the various methods involved in jib crane design and advancement of design and the analysis of jib crane to make it effective. The practices followed and measures developed to make high-rise construction a safer job will be listed in report. Some of the main benefits of the automated design include the following: Greater consistency of design; this makes manufacturing and field service easier. Ability to explore more alternatives; because design can be created in a shorter time, it allows designers to study more alternatives. 2.3 Gantt Chart Gantt Chart: Project on â€Å"Automating design of jib crane† TASKS Oct Nov Dec Jan Feb Selection of the Topic Submission of the Project Proposal Literature survey on the Topic Submission of the Interim Report Software development Conclusion and Recommendations Final Report Submission Chapter-3 Design and Calculation of Jib Crane 3.1 Design Concepts for Jib Crane Jib cranes, a free standing or portable jib crane is an economical solution for moving materials within an individual workstation, for transferring materials from work area to work area, or for use as an auxiliary lifting device under an overhead crane. Jib cranes are designed and manufactured in four styles: Free standing or portable jib cranes Wall bracket tie rod supported jib cranes Wall cantilever jib cranes Mast style jib cranes (top and bottom supported) Articulating jib cranes are also manufactured for positioning loads in those hard to reach places where most Standard jib cranes cannot reach. An articulating jib crane can move loads around corners and columns, reach into machinery, and service an area from the closest pivot point to the end of the boom allowing 360 º of operation. Another jib crane is the workstation jib crane. From self-supporting to wall mounted, workstation jib cranes provides economic, supplemental lifting coverage with 200 º or 360 º of rotation. Features Standard jib cranes range in capacity up to 5 tons and spans to 20 feet. Jib cranes feature on unique trussed boom design, which offers longer spans for custom jib crane designs. Free standing and mast type jib cranes offer 360  º rotations. Wall mounted offers 200 º of rotation. Design Factor The standard capacity rating of a jib crane represents the net rated load of the hook at the hook of a hoist of the same rated capacity as the crane. The design factor for the stresses in the crane is based on the capacity plus 25% of the rated load for impact and 15% of the rated load for the weight of the hoist and trolley. This was used all along with the average yield stress of the material to find out the type of the design. [Juvinall, 1991] This design provides a margin to allow for variations in material properties, operating conditions, and design assumptions. No crane should be supposed to ever, in any circumstance, be weighted beyond its rated capability. Service Factor The maximum weight of the application should match, NOT exceed, and design weight. The capacity rating is dependent and based on a design load. The jib crane design criterion allows the least amount of deflection so as not to hamper the performance of the jib crane. 3.2 Design of a Jib Crane The unit system of choice is normally SI. For this design, though, the BG (British Gravitational) system is chosen because the dimensions of most acquired components are in inches. We are doing analysis and design of a 30-foot, 1 ton jib crane. Requirements The crane must meet the following criteria: Should have a capacity of one ton (2000 lb). Should have a 30 feet length. Should be able to mount on the existing building structure. The design load is 2700 lb, defined as follows: Pd = 2000 lb + 25% overload + 200 lb trolley weight The length of the crane is taken as that of the main beam. The entire crane will arrive at approximately 372 inches from its pivot point. The alternative concepts are already evaluated earlier. We are taking the crane with two tension rods. 3.2.1 Reaction Force Calculations Before detailed design could begin, it had to be determined whether the building structure could support the new crane. This can be accomplished by drawing a free body diagram of the overall crane structure, and calculating the forces that would act on it. The design load should be positioned in the worst-case position hence at the end of the main beam. Since the weight of the crane makes a noteworthy horizontal reaction force, its main structural components were specified for this practice. A single 200-lb tension rod, attached at 20 feet from the root of the main beam The weight of the vertical member (eight feet at 25 pounds per foot) was used in calculating the vertical reaction force, but was not deemed significant in calculating the horizontal reaction forces. Minor components e.g. mounting brackets and pin- fasteners, are not going to consider. The calculations solved on paper, give the following results for The 10 Inch diameter S10at25.4 the beam: Horizontal reaction force: 12,556 lb Vertical reaction force: 3854 lb 3.2.2 Design of Main Beam The main beam is the most structurally significant part of the crane, and thus was the first to be designed. The maximum stress of a crane has to be less than one fifth of the ultimate strength of the steel. The maximum deflection should be less than 600th part of the length of the crane. Manual calculations proved that the 8-inch beam would buckle under the compression made by applying the design load at the end of the beam. Buckling load A Beam, 360 inches long, meets both stress and deflection guidelines when used with two tension rods. The maximum stress and deflection, when the load is on the end of the crane, are as follows 3.2.3 Primary Structure With the main beam specified, the rest of the crane was designed around it. A model was constructed consisting of the main beam, the vertical member, and the tension rods, which were arbitrarily attached at 15 and 25 feet from the root of the main beam. Manual calculations performed later confirmed that these were appropriate attachment points. For the sake of simplicity, the vertical member can be specified as the same cross section as the main beam and the vertical member is 96 inches long. Rod tension Assume main beam pinned at one end 3.2.4 Minor Components Connecting the Tension Rods to the Main Beam The tension rods are connected to the main beam using a clevis, which is pinned to a mounting plate welded to the main beam. This clevis is having a tensile load rating of 45,600 lb which allows a considerable safety factor. The clevis pin is protected with a 1/8†inch cotter pin. Double-shear calculations show it to be more than strong enough. Clevis Pin The clevis mount was designed over-large, to fill up the clearances provided by the clevis. The calculations show that the clevis mount, like the clevis itself, provides a significant margin of safety. Clevis Mount Su = 58000 psi Sus = 33640 psi F = 21658 lb th = 2 ½ in ro = 21/8 in ri = 7/8 in d = 1 ¾ in The tension rod is connected to the clevis through a turnbuckle and since the clevis has a rod diameter of 1 ½ inches, the stud must be turned down from 2 ¼ inches to 1 ½ inches. The lower end of the tension rod should be threaded for inclusion into the turnbuckle. Specification of Bearings Using the overall horizontal reaction force as the radial load, the bearings can be specified. The bolt holes in the flange of this bearing are placed in the identical position. Design of Welds The weld connecting the tension rod to the top of the vertical member requires individual explanation. The tension rod on the crane is bent, and then welded to the top of the vertical member of that crane After placing one rod on top of the vertical member, welds 1 and 2 should consist of a groove weld, then a fillet weld. Weld 3 should use the same pattern subsequent to the second rod is being placed. At last, weld 4 is a groove weld. All welds should fill up obtainable clearances. 3.3 Design Modification: For each handling device, the two horizontal DOF differ in feel. For the jib and gantry cranes, motion along the trolleys direction of travel requires relatively little force. Similarly, on the bridge crane, motion along the bridge is relatively easy. But for the jib crane, moving perpendicular to the booms length is complicated by the booms rotational inertia and the boom pivots friction. For the gantry crane, this perpendicular motion is very difficult due to the large inertia of the crane, and as stated earlier, often requires power assist. Finally, for the bridge crane, it is the large inertia of the bridge and resulting increased rolling resistance in its trolleys that make the perpendicular motion more difficult. Low speed power assist has been added to each of these difficult motions: rotation of the boom on a jib crane, translation of a gantry crane, and translation of the bridge along the fixed rails of a bridge crane. The control of this power has been limited to simple push button on/off switches and control algorithms which provide a slow start and stop to minimize load swing. The anisotropy exhibited in the different motions remains. This lack of isotropy makes it difficult for workers to move an object from point to point. The worker must constantly vary the applied force as the desired direction of motion changes. To think of this phenomenon in different terms, consider a round stick half immersed in a pool of water. It is very easy to move this stick through a curved trajectory. The forces resisting the motion are independent of the motions direction. Now consider a paddle (which cannot be rotated) immersed in the pool. It is considerably more difficult to move this paddle through the same curved trajectory. The human must continually adjust to the changing resistance forces. Increasing the viscosity of the fluid will exacerbate the problem. This is analogous to increasing the size and/or load of a material handling system.[Franklin, 1994] Hence thus, ideally, overhead material handing devices would exhibit isotropy. That is, the feel of the device would be independent of the direction in which it was pushed. So the next objective is to advance the design of jib crane which is intelligent power assist jib and making the design calculation by Microsoft excel itself. For this design the drawing has been done for some parts and shown below. The rest of the analysis will be done in the final report. In the modified design we put some control sensor for the motion of the jib crane.

Assess the Claim That the Main Function of Education

Assess the claim that ‘the main function of education is to maintain a value consensus in society' Functionalists believe that education is a value consensus, which means that the majority of a society agree with this statement. For example, inadvertently, people in the UK agree that wearing clothes is a norm as is education. Education has many purposes such as secondary socialisation of children and allocation of roles, because of the meritocracy which education is also seen as.Functionalists, like Durkheim, believe that teaching about history in schools creates a link between the individual and society. This link allows the individual to feel ‘part' of the society and therefore is more likely to support this. For example, in the U. S children are taught about the founding fathers and give the pledge of allegiance daily. Also, this is used with religion, in the U. K many schools says prayers and sing hymns and other religious songs. This, often, instils the idea of relig ion into the child's mind and it becomes a part of the child.However, teachings such as these can be seen as deviant and unwanted by parents because of how these things are treated as ‘norms' whereas they might not be in the home. This creates social solidarity because of the increased number of shared ‘norms and values'. Furthermore, Parsons says that school is the bridge between family and the wider society. Because in the family you are treated as an individual based upon particularistic traits whereas in society you are based on your merits.School is a blend between the two and allows a consensus of your merits and your personality. However, that blend is more between students and students than students and teachers. Teachers base students more on their merits, hence the meritocracy of school and the wider society as it is a quicker and easier way to assess people. This lead to the beginning of the education triage where pupils where ‘streamed' into classes of varying difficulty depending on their intelligence. However, Marxist's like Althusser, Bowles and Gintis argue that the role of ducation is the â€Å"reproduction of labour power† i. e. a workforce. This is enabled by use of the hidden curriculum – This is where ‘norm's such as doing repetitive tasks, not complaining and maintaining order in a class are taught but not formally as these are merely blended into every lesson. This is further exaggerated by schools legitimising and justifying inequality. This prepares students for the world of work where they are exploited for cheap labour and do as they're told as indicated by the hidden curriculum.They are also prepared for the inequality between them and their bosses in the social/economic hierarchy and accepts their positon. Legitimation of inequality; helps to justify and explain the system of social inequality in a capitalist society, helps people come to terms with their position in society and therefore reduc es the discontent and opposition to inequality. Althusser saw the role of education as a reproduction of technical skills and a reproduction of the ruling class ideology. . e. the dominant beliefs and values which is the wealthy minority 1% and the majority 99%. This allows the 99% to accept the 1%'s ideology. To prevent rebellion against capitalism, people must believe that the ruling class ideology is beneficial to themselves. This done by a number of ideological state apparatuses like the media, religion and education. These outlets of information can control masses because they have been ‘trusted' staples of society which are seen as beneficial.However, all of these outlets show the ruling class ideology and justify the capitalist system. The system can give several messages out to society such as behaviour, fashion, education standards, when to accept or submit to authority and to accept your place/position in society. Despite, these views Marxist's have been seen as too deterministic. As, the give education more credit for its influence on children. For example, the hidden curriculum may not exist and many children don't care for rules, authority and choose to rebel at these things.Whilst the hidden curriculum maybe exaggerated, the formal curriculum maybe under exaggerated as it is not entirely designed to benefit ruling class ideology as with subjects like philosophy, sociology and arts which are designed to encourage various views and opinions with critical thinking on how and why. Neo-marxists, like Willis, show that some students at school who are rebellious and prioritise â€Å"avin' a laff† are the ideal candidates for the ruling class ideology as they treat education as a barrier between â€Å"avin' a laff† and socialising.Because they prioritise their friends they lose the benefits of education and are forced, in order to survive, to accept work which maybe dull/repetitive (as taught by the hidden curriculum). Often, the type work these people undergo are manual labour jobs which enable the ‘lads' to be together and â€Å"av' a laff†. The end product is a capitalist society getting a proportion of the population doing dull work and the ‘lads' are able to stay together as they have created their own class position.Durkheim, also argues that education prepares young people for adult roles such as learning to cooperate with people who they might not like. Schools trains people to follow a set rules which accommodate tolerating people who they don't like. Functionalists, assume that stratification/some sort of social hierarchy is vital and inevitable. Because there are only limited places for top jobs. By a meritocracy which allows people to be test judged on ability those with the highest ability are about to be placed in jobs which match their talents/abilities.

In this time, society was governed by strict moral codes. The Gothics would escape into a world of dark, supernatural and wild passions. The word Gothic meant barbarous and wild and many writers liked to involve these elements in their novels.

Bronte describes this room in huge depth, and gives the reader a strong visual idea of what it looks like; massive pillars of mahogany and curtains of deep red damask. Jane also describes it as chill and lonely due to the fa ct that this was where Mr Reed breathed his last. It is also very Gothic when Jane sees the ghost in the room, given that many Gothic novels have monsters or ghosts in them. Oh! I saw a light, I thought a ghost would come. This is a very significant moment at Gateshead, and Bronte uses descriptive language to build up the suspense and tension, My heart beat thick, also I was oppressed, suffocated. The next location Jane goes to is Lowood. The school is described as a large and irregular building, It is very run-down and decrepit, and far away from any village or town. Bronte describes it to have a very dreary silence, with great low-ceiled, gloomy rooms It is also described as grey and old with a church-like aspect. This setting is obviously very Gothic.

The Human Nervous system is the most complex of the body, it is our essential controller; this system is independent and governs our cerebrations, emotions, and functions. It additionally avails with sending, receiving, and transforming nerve impulses. The sensory system incorporates nerves, tactile organs, the mind, and muscles. This system is furthermore classified as the visceral motor system separating it from the somatic motor system. The most essential organs of the ANS are named the viscera of the Thoracic and abdominopelvic cavities. With this association we are incapable of determining or feeling its existence in our bodies as it works unwillingly. This system explains our flight or battle reaction, watching our body amid rest and reclamation, and observing our heart rate and body temperatures on a steady premise. The ANS has two subsystems, known as the Sympathetic and Parasympathetic; these two systems vary somehow, the sympathetic nervous system increments vigilantness, heart rate, blood glucose focus, circulatory strain, and blood stream to cardiovascular and skeletal muscle, and additionally lessening blood stream to skin and digestive tract. Then again, the Parasympathetic division has a cooling, impact on a large portion of the body s capacities. This is kenned as the resting, and processing state.

There are segments all throughout the body of the daphnia however they are not visible to the naked human eye. There is a visibleRead MoreHow The Nervous System Affects The Human Brain990 Words   |  4 Pagesthe human brain. Every neuron can receive 1000 electrical impulses from other neurons. Impulses that all come at the same time are added together and, if they are strong enough, they can generate  electrical discharge, which is known as  action potential o r a nerve impulse. Neurons have a cell body or soma. Additionally, they have myelin.  Myelin allows nerve impulses to move quickly from one neuron to another, which makes  rapid signal transmission possible.  It is a critical part of the nervous systemRead MoreElectronic Devices And The Human Central Nervous System1417 Words   |  6 PagesElectricity in both everyday electronic devices and in the human Central Nervous System is created through the flow of charged particles. However, in electric circuits, charge is carried by moving electrons through a conductive wire, whereas in the brain, impulses are carried by ions, or charged molecules. Electrical signals in the brain mainly take place in neurons, which are nerve cells that specialize in transferring nerve impulses. Changes in the concentration of ions in a neuron cause changesRead MoreThe Comparison of Nervous Systems in Humans, Cnidarians, Flatworms, and Annelids1671 Words   |  7 PagesComparison of Nervous Systems in Humans, Cnidarians, Flatworms, and Annelids The nervous system is one of the most important organ systems in the body. It is in charge of all of the things that happen within the body. Being responsible for receiving sensory input from internal and external stimuli, integrating and processing information, and generating output, it would be hard to survive without a nervous system; however, there are different types of nervous systems in various organisms. Humans, cnidarians
