| Abstract:A detailed model of the common fixing pedestal of gas turbine generator set was established. By means of finite element analysis, the optimization design of the model is accomplished. In the course, vibration modal analysis of common fixing pedestal in free and fixing state was carried out, and the modal parameters were obtained. Therefore, the design stiffness and structural rationality of the common fixing pedestal of gas turbine generator is verified. |
