The invention provides a stainless steel metro car body structure with replaceable modules. The metro car body structure comprises a chassis steel structure, a car roof steel structure, a side wall steel structure, an end wall steel structure, a cab framework structure, an end crushing area and an energy absorption structure. The ground body vehicle body structure has high strength and high safety performance, and the vehicle body structure does not yield under the working condition that the compression load of the end portion is 1800 kN; when destructive accidents such as collision occur, only local replacement or maintenance is needed, the problem that the whole vehicle body system is not suitable for maintenance is solved, the cost is effectively reduced, the service life of an accident vehicle body is prolonged, and the design life of the optimized vehicle body structure can be prolonged to 40 years through simulation analysis and line test data verification.
本发明提供一种带有可更换模块的不锈钢地铁车体结构,地铁车体结构包括底架钢结构,车顶钢结构,侧墙钢结构,端墙钢结构,司机室骨架结构,端部压溃区和吸能结构;本次发明的地体车体结构,具有高强度高安全性能,端部压缩载荷能够实现1800kN压缩载荷工况下,车体结构不发生屈服;在发生碰撞等破坏性事故时,仅需对局部进行更换或维修,解决了车体系统整车不适合维修维护的难题,有效降低成本,提高事故车体的运营寿命,优化后的车体结构,经仿真分析和线路试验数据验证,车体结构的设计寿命可提高至40年。
