摘要
建立了某集中驱动式纯电动车的电机悬置系统6自由度刚体模型,进行了其固有特性分析和瞬态工况下的动态响应仿真;以能量解耦率为优化目标,兼顾悬置动反力和位移等指标,优化了该悬置系统元件的刚度,使其瞬态振动性能也得到改善。
The electric vehicle’s powertrain mounting system rigid model of six degrees of freedom is established.Then its inherent characteristics is analyzed and simulation of its dynamic response is conducted.The optimization goal is a better energy decoupling rate,the dynamic reaction force of the suspension and the displacement of the powertrain are also considered.In the end,the stiffness of the suspension system components isoptimized,and the transient vibration performance of the suspension system is improved.
