摘要
建立了ＤＫ２０型地铁车体结构整体有限元计算模型，对该车车体进行了静力计算、结构修改分析、结构动态特性计算和重量、重心及转动惯量计算，并对地铁车体结构强度和刚度评价标准进行了探讨。
In this paper,the integral finite element computing model for the subway carbody structure type DK 20 is established.Static computation,structure modification analysis,dynamic characteristic computation of structure,as well as computations on weight,center of gravity,moment of inertia of this carbody are implemented,and the evaluation standards for strength and stiffness of the subway carbody structure are inquired into.
