基于ADAMS/Insight某型电动车悬架仿真优化研究

摘要

Based on vehicle dynamics simulation software ADAMS/Car,this paper builds the dynamic model of the double wishbone of the electric car,selects eight key suspension hard-point coordinates as design variable,five suspension positioning parameters as the optimization target,to make the simulation analysis and the optimize-iterative calculation with ADAMS/Insight and then analyzes the change of the suspension positioning parameters before and after its optimization.%以ADAMS/Car车辆动力学仿真软件为基础,建立某型电动车双横臂式独立前悬架动力学模型,选取悬架的8个关键硬点坐标为设计变量,5个悬架定位参数为优化目标,联合AD-AMS/Insight对悬架进行仿真分析和优化迭代计算.对优化前后悬架定位参数的变化进行了分析.
