Abstract: In the modern automotive industry, the performance of the suspension system is directly related to the smoothness and comfort of driving, and the shock absorber, as its core component, plays a crucial role in reducing vibration and enhancing the ride experience. With the help of Inspire software and topology optimisation technique, the article introduces a feedback mechanism in the optimisation step to realise the dynamic adjustment of the design process, and designs a three-stage solution selection process to ensure the efficient and effective lightweight design of the shock absorber structure, so as to improve the performance and material utilisation of the shock absorber design. The optimal lightweight design under different scenarios is explored through the control variable method, which provides a feasible solution for the innovation and design of automotive shock absorbers.
