摘　　要：针对船用发电机的结构开展了一系列的结构振动分析和结构优化工作。通过振动测试、实验模态分析和有限元仿真的结果对比,定位了结构振动突出的产生原因,并验证了整改措施的可行性。本文总结了刚性电机转子设计、端盖配合、机座结构设计的经验,为类似电机的声振结构优化设计提供指导。A set of analysis on structural vibration and structural optimization are carried out on agenerator. By comparing the results from vibration test, experimental modal analysis and finiteelement analysis, the reasons causing vibration peaks are located, and the solving measures areverified to be feasible. This work concludes the design experience on rigid rotor critical speed, fittolerance of end-shield and structural topology of stator frame, which provide guidance for thestructural optimization design of motors with similar structure.
