摘　　要：电机整机的振动特性在很大程度上取决于其子结构的动态特性。在这项工作中,用模态分析技术确定了电机机壳、端盖、轴承和转子的动态特性,然后运用机械阻抗合成法计算出整机的动态特性。研究结果使通过结构修改来降低电机的振动噪声成为可能。The vibration behaviour of the whole motor is to great extent determined by the dynamic properties of its substructures. In this work, the dynamic properties of housing, end covers, bearings and rotor of the electric motor were determined using modal analysis technique, then the mechanical impedance synthesis method was applied to calculate the vibration behaviour of the whole motor. The results obtained make it possible to reduce the motor vibration and noise by means of structure modification.
