| Abstract: | Taking the structural modal analysis of EMU aluminum alloy car body as the entry point,the influence of structural parameters of sidewall window on car body modal is mainly studied.Looked at the window structure of a certain type of EMU,a finite element model of the aluminum alloy car body is established.Then,the Lanczos method is used to obtain the first 6 modal frequencies of vehicle body.Through a comparative analysis of the weight and the modal of car body,window design methods for improving the car body modal are put forward. |
