| 摘 要： | 四轮独立驱动电动汽车通过轮毂电机直接驱动车辆,电磁力输出波动直接作用于车轮和悬架,将导致车辆的动力学性能恶化。利用傅立叶级数法,建立考虑不平衡径向力的悬架系统机电耦合模型。在此基础上,提出了电磁主动悬架多目标粒子群优化设计方法,以抑制轮毂电机驱动电动汽车的振动负效应问题。研究结果表明:通过对主动悬架构型以及控制器参数的多目标优化设计,能有效削弱振动负效应,改善电动汽车的安全性和舒适性。

| Abstract: | The four-wheel electric vehicles drive the vehicle independently through the in-wheel motor, which causes the electromagnetic force output fluctuation directly acts on the wheels and the suspension, resulting in deterioration of the vehicle''s dynamic performance. The Fourier series method was adopted in this research to develop an in-wheel motor-electric vehicle (IWM-EV) co-model with active suspension.And then, a co-operative parameter optimization via (multi-objective particle swarm optimization) MOPSO was proposed to weaken the negative vibration effects caused by electromechanical coupling in in-wheel motor system. The simulation results has testified its effectiveness. |
