摘要
以动车组铝合金车体结构模态分析为切入点,重点研究侧墙窗户结构参数对车体模态的影响。以某型号动车组的窗户结构设置为研究对象,建立铝合金车体有限元模型,通过Lanczos法获取车体前6阶模态频率,并通过对车体质量和模态的对比分析,提出有利于提高车体模态的窗户设计建议。
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.
