Abstract:
The senior-level Mechanical Engineering capstone students partnered with Goodyear Tire Proving Grounds in San Angelo, Texas in order to design and construct a new concept design of an existing tire testing trailer. The major requirements given to the team from the client were to design a testing trailer capable of generating a mu-slip curve for a commercial tire (approximately 7,000lb tire load / 14,000lb axle load.). Utilizing structural and mechanical engineering theory, a preliminary design was developed and simulated using the finite element analysis method. The developed model was then manufactured at a half scale and tested for various parameters in order to validate the model being used. AISI 1018 Carbon Steel Tubing rated for 52 ksi yield stress.was the decided material for the prototype. With the model validated the team they had freedom to make changes to the model as needed. This report will act as a description of the trailer, provide a history of the model as it developed, describe the manufacturing process, describe tests that were ran, and conclusions about the proposed model. The Driving 5 designed and manufactured a solution to Goodyears need of a commercial tire testing trailer and provided a detailed report to answer any questions and enhance important aspects of the project.
