摘　　要：为探索机电耦联的研究方法对电机驱动车辆动力传动系统是否适用,将某电动车动力传动系统的机械振动模型简化为两自由度系统模型,对其在左端边界为自由、线性扭簧及非线性扭簧三类条件下的固有特性及响应进行了分析.结果表明,由扭簧模拟的机电耦合系统与不考虑机电耦联的系统相比,动力学特性发生明显改变,证明了进行电机驱动车辆动力传动系统机电耦联非线性振动研究的必要性.In order to explore the applicability of the electromechanical coupling method for the investiga- tion of motor vehicle power transmission system, a mechanical vibration model of electric vehicle power train was simplified into two degree freedom model. Its inherent characteristics and responses were analyzed in conditions of free left end border, left linear torsion spring and nonlinear torsion spring. Results show that dynamic charac- teristics of the electromechanical coupling system simulated by torsion spring changed significantly compare with the traditional system. It is proved that using electromechanical coupling nonlinear vibration study for motor driv- en vehicle power system is feasible.
