为研究电动汽车电机控制器的疲劳可靠性，首先利用 HyperMesh 软件建立精确的有限元模型，在 ANSYS软件中进行模态分析，得到关心的模态阶数与振型特征，再以振动试验标准为基础，采用 ANSYS nCode DesignLife软件建立正弦扫频疲劳仿真模板，分析 X 、Y 和 Z 三方向的振动疲劳损伤，得出结构薄弱部位的疲劳寿命结果。最后通过对电机控制器样机的振动试验检测，验证了仿真分析方法的可行性。

In order to study the fatigue reliability of motor controller for electric vehicle,the accu-rate finite element model is built by using HyperMesh software,and then the concerned modal or-der and vibration characteristics are obtained by modal analysis in ANSYS software.The sine sweep fatigue simulation template is built in ANSYS nCode DesignLife software based on vibra-tion test standard.The fatigue damage of X ,Y and Z direction vibration and fatigue life of the structure weak parts are obtained.Finally,the feasibility of the simulation method is verified by the vibration test on motor controller sample.
