Abstract:
Being one of the key rotating components of an automobile, the lightweight design and reliability of the wheel directly impact the overall performance of the automobile. When optimizing the lightweight design of the entire wheel system, it is crucial to consider how structural changes affect its fatigue performance, impact resistance, and other mechanical properties. Therefore, a reliability-based lightweight design method is employed to optimize the racing wheel system, ensuring it meets the performance requirements of automobile while shortening the design process and providing a comprehensive optimization scheme. A parametric model of the wheel system is established using data from the participating automobile, and mechanical analysis of the designed wheel is performed through finite element methods, subsequently leading to topological optimization based on the results. The fatigue life is assessed through impact and bending fatigue tests, determining whether the designed wheel system meets the necessary performance criteria and providing theoretical support for wheel design and practical applications in the participating automobiles. This method is also applicable to the lightweight design of other mechanical components.
