| Abstract: | The modal analysis on fixing pedestal of diesel generator set was done under free-free boundary conditions by means of finite element analysis software ANSYS,so the modal parameters of each order were obtained and compared with the results of experimental modal analysis,the simulation model was proved properly.The research has given a gist for optimal design on the structure of fixing pedestal. |
