摘　　要：对某船用汽轮发电机组公共底座进行了模态仿真分析,并进行了模态测试。测试结果与仿真分析结果达到了吻合,说明公共底座有限元建模方法可行,有限元模型满足工程精度要求,这为进一步分析整体汽轮发电机组动力特性奠定了基础。Modal analysis and modal test on a ship steam-turbine generator set are carried out. The results of simulation analysis and testing achieve a good agreement. It shows that the method of finite element modeling on the pedestal is feasible. The finite element model of pedestal has sufficient accuracy for engineering analysis. It lays the foundations for further overall analysis on the dynamic characteristics of steam-turbine generator set.
