The Tire Structure - Case Study Example

Problem First report This report was meant to cover the design and establishment of a method that could be used to burnish a wet and thin strip that could save on time while maintaining even burnishing of the entire tire surface. In this, the strip would be made wet by sprinkling with water; this would be done by a source that guarantees a continuous supply of water at a controlled rate. The tire would then be moved along the strip with some load on it in different ways i.e. methods and at different speeds, the method that produces notable burnishing on the tire is then chosen over others. This was also to address the uniform distribution of the vertical load on the two wheels through the creation of a design that could vary the normal force and rotational velocity applied to the burnishing tire to ensure that one wheel is not overwhelmed which might lead to the bursting of the tire on that wheel. Second report The track surfaces used for wet traction tests develop non-uniformity in grip levels over time, the antilock braking system prevents the wheel from skidding in low traction situation, the main aim of the project under this report was to develop an implement that can be attached to a tractor and powered by the tractor’s power take off. This implement was to function in the exact fashion as an ABS system. This was to ensure that even at times when the strip surface had developed less grip capability the tire would still hold on to the track without skidding. i.e. To provide constant grip over time. Third report. In the project under this report, it was required for the team to create a design for an implement which can be attached to a tractor and driven by the tractor power take-off, which could be used to rotate the tires so that it could burnish or scrub the surface of a test track as the tractor moves the implement along the surface. In order to avoid constant scrubbing this implement was to offer the capability to change the vertical load on the tire, the goal is to enhance the effectiveness of the burnishing process by increasing the time period between the needed burnishing, decrease the time required to burnish, and achieve the target coefficient of friction consistently over the entirety of the test area(L. Beaver, A. Drew and J. Leitzsey). Solution Description First report. The solution to this problem was based majorly on the constraints on the design of the traction method, the solution to the constraints mainly focused on speeding up the current burnishing process and providing more even coverage while creating a design that would be easy to operate and maintain. The solutions to the criteria should provide for the following: precise/even burnishing variable pressure easy to manufacture durable easy to transport easy to maintain Should not damage track/environment Should prevent swaying or drifting on the track Should be safe to use Should minimize user interaction Second report The solutions to this problem include the maximum adherence to the implementation of the constraint requirements. The constraints include; Have a contact pressure equal to 18 psi Not exceed a width of 15 feet. Fit on a roll back/flat bed truck. Attach to a three point hitch. Burnish in a direction consistent with normal ABS braking test path. Be able to evenly distribute banishments across the test path. . Third report The solution to this problem includes the proper implementation of the constraint requirements of the design, when the final design has all the characteristics as per the constraint then it is considered as the solution, the constraints are; incorporate the simultaneous use of at least 2 tires, maintain a contact pressure of 18 psi between the tire and track surface within a ±4 psi tolerance, maximum width of 15 ft, burnish in the direction of braking, be able to keep 2” away from water system without causing damage, operate equipped with a matching set of tires on apparatus at one time, and be able to operate with a John Deere 5420 (L. Beaver, A. Drew and J. Leitzsey). Discussion on the Focus of the Report First report This report was meant to cover the design and establishment of a method that could be used to burnish a wet and thin strip that could save on time while maintaining even burnishing of the entire tire surface, the goal of the final design was to create a rotating tire system(Whitehead, Hudson and Klingman). The process involves: design selection which is also divided into; functional decomposition- concerned with the ease of use and maintenance of the design and safe interface between the design and operation, initial designs which involved finding out how many tires are to be used in the design, final design which is based on a dual rear wheel assembly of a Ford 8.8in rear end. Second report The problem is that the track surfaces used for wet traction tests develop non-uniformity in grip levels over time. The product needed is an implement that can be attached to a tractor and powered by the tractor’s power take off. The process involves definition of the desired functions of the track burnisher, a brainstorming session and placing the ideas generated in a morphological order. Third report The problem was the creation of a design for an implement which can be attached to a tractor and driven by the tractor power take-off, which could be used to rotate the tires so that it could burnish or scrub the surface of a test track as the tractor moves the implement along the surface and offer the capability to change the vertical load on the tire. The product is an implement attached to a tractor and driven by a tractor power take off. Discussion on the readability with justification First report Considering the readability of this report it is found out that it is less readable, the reader finds it abit boring to go through the report since that even the drawings used are not colored hence not appealing to the eye, the use of colors attracts the reader’s attention to a particular drawing hence creates higher concentration leading to adequate readership. This is justified by the existence of un colored drawing from figure 2.1 through to figure 3.2. Second report This report is quite readable since it contains all the appealing visual drawings which can attract the attention of the reader to a particular point, the only problem is that the author never paid so much attention to the rules of writing reports, the addressee and the addressor details should have been inclined to the left hand side, this makes it easy for the reader to follow the next line of the first paragraph without straining, this is justified by the placement of the above mentioned details on the right hand side of the report. Third report This report is quite readable; it adheres to all the necessary requirements of a good report, it contains the virtual appeal as shown by the drawings. Work Cited Beaver, Luke, et al.
