摘　　要：建立了某汽车电动轮的Simulink模型,在B级随机路面输入下,在时域和频域上分析非簧载质量的增加对汽车车身加速度、悬架动挠度、车轮动载荷的影响。在ADAMS中对影响车身加速度的因素进行灵敏度分析,建立响应面模型并进行优化。对比优化前后的仿真数据,所优化的设计参数得到改善,验证了优化的准确性和可行性,为之后的平顺性设计提供参考。The Simulink model of the electric wheel of an automobile is established.Under the B-level random road input,the influence of the increase of unsprung mass on the vehicle body acceleration,suspension dynamic deflection and wheel dynamic load is analyzed in time domain and frequency domain.In ADAMS,the sensitivity analysis of the factors affecting the body acceleration is carried out,and the response surface model is established and optimized.Compared with the simulation data before and after optimization,the optimized design parameters are improved to verify the accuracy and feasibility of the optimization,which provides a reference for the ride comfort design.
