The invention discloses a subway carriage side wall design method and a subway carriage side wall. The subway carriage side wall is formed by splicing side wall modules. Each side wall module is composed of a side wall body, a reinforcing rib, a cross beam and a mounting base, and each side wall body is of a sandwich structure composed of a panel and a core material. Simulation design software is used for conducting simulation design, the stress state of each part of the side wall body is obtained through finite element analysis, and therefore core materials adopted by different parts of the side wall body are determined, and the positions and sizes of the installation beams and the reinforcing ribs on the side wall body are determined. The structure and function integration of the subway carriage side wall is achieved, the light weight of the subway carriage side wall is achieved on the premise that the strength and rigidity of the subway carriage side wall are guaranteed, and the production cost is reduced.
本发明公开了一种地铁车厢侧墙设计方法及地铁车厢侧墙,地铁车厢侧墙由侧墙模块拼接组成。侧墙模块由侧墙本体、加强筋、横梁及安装座组成,侧墙本体采用由面板与芯材组成的夹芯结构。利用仿真设计软件进行仿真设计,通过有限元分析得出侧墙本体各部位的应力状态,从而确定侧墙本体不同部位所采用的芯材材质,并确定安装梁及加强筋在侧墙本体上的位置及尺寸。以实现地铁车厢侧墙的结构功能一体化,在保证地铁车厢侧墙强度和刚度的前提下实现地铁车厢侧墙的轻量化,降低生产成本。
