Abstract

Abstract

The strength design of vehicle suspension key fastener is mainly dependent on empirical formula currently, thus it is difficult to ensure the reliability of design. How to ensure adequate strength of fastener has been the key problem of key fastener design and selection. Firstly, four analytical models of longitudinal, lateral, vertical and composite vehicle models under extreme conditions were established. Parameters of vehicle model were modified according toteh results of road testing, and tire forces were solved by using numerical methods. Then the suspension model in the ADAMS software was improved, and the key fastener forces under each extreme condition were obtained based on computer simulations.Finally, the strength design and selection for key fasteners were executed according to the maximum force. Application examples show that this design method is able to guarantee the strength design and selection of suspension key fastener with sufficient reliability and it meets the requirements of each extreme condition.
