摘要

针对轮边驱动电动车存在的轮毂电机振动问题，以开关磁阻电机（SRM）为例，分析了电机垂向激励对车辆性能的影响。探讨分析不同车速工况下路面和电机两种耦合激励对轮边驱动电动车垂向动力学特性的影响。研究表明，电机激励对车辆垂向性能的影响主要集中在低车速范围。此时，电机激励频率接近悬架系统固有频率，容易引发车辆共振。鉴于电机激励具有的周期性特点，提出了基于FxLMS算法的主动悬架控制方法，进而抑制电机垂向激励产生的车辆垂向振动负效应，仿真分析验证了算法的有效性。

Abstract

In view of the existing vibration of the in-wheel motor electric vehicle(IWM-EV), taking the switched reluctance motor (SRM) as an example, the exciting force in the vertical direction was analyzed. Meanwhile，the negative effect of the vertical vibration on vehicle performance was discussed. The simulation results show that the vertical vibration effected by the SRM exciting force was concentrated in low speed. In this case, the frequency of SRM exciting force was close to the frequency of vehicle vertical vibration. So, the exciting force can induce vehicle resonance easily. According to the periodic characteristic of the exciting force, the FxLMS algorithm based on active suspension was presented to restrain vertical vibration. The simulation verified the effectiveness of this method.
