Abstract: The bump stop is a critical component in the passenger car suspension system, significantly influencing ride and handling. Starting with an analysis of the suspension elastic characteristics, this paper introduces the structure of the bump stop, its force conditions, and the decomposition of forces. From the perspective of modular development, it describes the method of designing bump stops using computational and simulation approaches. Following this method, the bump stop was designed and validated, proving the effectiveness of the design approach. The research has certain engineering practice value and provides reference ideas for related fields.
