摘要
在某车型后悬架硬点前期开发中,确定了整车后悬架硬点设计开发以悬架K&C特性作为优化设计工况。基于工程经验和四连杆式悬架特点,选择对悬架K&C特性有较大影响的悬架设计参数,通过对比分析,选用合适的DOE方法、近似模型法和优化算法,实现了整车后悬架硬点的优化设计,提高了整车开发效率。
In the advanced development of a vehicle rear suspension, suspension K＆ C characteristic is defined as optimal design conditions for vehicle rear suspension hard point design and development. Based on engineering experience and features of four-link type suspension, suspension design parameters which have substantial influence on suspension K＆C characteristic are chosen. By comparison and analysis, appropriate DOE approach, approximation model method and optimization algorithm are chosen for rear suspension hard point optimization, which improve the vehicle development efficiency.
