摘要
针对传统赛车进行电动化改造时,簧载质量和零部件布置的变化严重影响悬架运动学特性的问题,提出了一种电动赛车不等长双横臂悬架系统优化方案。首先综合考虑质量、偏频及布置干涉因素,在传统悬架系统基础上得到了不等长双横臂悬架的初步模型;结合电动赛车悬架试验要求,进行轮跳试验;进一步依据试验仿真结果确定了10个优化变量参数,然后以车轮定位参数和侧倾中心高度为优化目标,利用ADAMS Insight模块进行硬点优化。结果表明,优化后的不等长双横臂悬架运动学特性满足设计要求,验证了提出的优化方案切实可行。
Aiming at the problem that the changes of spring mass and parts layout seriously affect the kinematic characteristics of suspension during the electric transformation of traditional racing cars,an optimization scheme of unequal length double wishbone suspension system of electric racing cars is proposed.Firstly,considering the factors of mass,frequency offset and layout interference,the preliminary model of unequal length double wishbone suspension is obtained based on the traditional suspension system;Combined with the experimental requirements of electric racing car suspension,wheel jump experiment is carried out;Further,10 optimization variable parameters are determined according to the experimental simulation results,and then the hard point optimization is carried out by using Adams/Insight module with the optimization objectives of wheel alignment parameters and roll center height.The results show that the kinematic characteristics of the optimized unequal wishbone suspension meet the design requirements,and the proposed optimization scheme is feasible.
