摘　　要：以改善车辆平顺性与车轮接地性为目的,针对一种新型一体化单摆臂悬架减速式轮边电驱动系统,进行了基于Matlab及Adams的仿真分析。结果表明,轮边电驱动系统质心在单摆臂上的位置和车身平顺性有着非单调的复杂关系,其和车轮接地性的关系则是单调的,且电驱动系统的质心越靠近摆臂,与车身的铰接点车轮接地性就越好。Based on Matlab and Adams softwares, a novel trailing arm electric wheel drive system with reducer has been simulated and analyzed to improve the ride comfort and the wheel ground adhesion. The results showed that the ride comfort were non-monotonicly dependent on the position of the center of mass for electric wheel drive system while the wheel ground adhesion were monotonicly dependent on it. And the wheel ground adhesion were better as the motor was closer to the oscillation center of suspension.
