以电动车动力总成为研究对象，建立了动力总成传动系统和结构系统的动力有限元分析模型，综合考虑齿轮内部动态激励和电机电磁激励，对动力总成进行振动特性数值仿真。分析了切向电磁力以及齿轮啮合冲击力对系统振动特性的影响。利用半消声室转鼓试验台对动力总成进行振动试验研究，并与数值仿真结果对比分析，验证了仿真方法的正确性。

Considering the internal dynamic excitations of gears and the electromagnetic excitations of an electric motor,a dynamic finite element model for transmission system and structure system of an electric powertrain was established,and the dynamic responses of the powertrain were calculated with the numerical simulation method.The effects of tangential electromagnetic force and gear mesh impact force on the vibration characteristics of the electric powertrain were analyzed.A test bench was used to detect the vibration acceleration of the powertrain in a semi-anechoic chamber.Comparison showed that the simulated results agree well with the test data.
