针对南亚地区轨道客车的运用环境、运营习惯、线路条件及发电车顶层技术指标要求，研制了一种适配发电机组从侧部窗口采用叉车安装、拆卸、更换、检修作业的新型发电车车体结构。该车体结构以铁素体不锈钢（1.4003）为主体材料焊接构建，开发了大开度侧窗和发电机组底架滑动横梁结构，设计了内部隔墙间通长侧顶梁框架，设置了发电机组走廊安全栅栏，匹配了大开度侧窗快速拆卸式模块百叶窗，并扩展了车顶侧部散热窗。通过对新型车体结构仿真计算、车体静强度试验、车体模态试验、整备车辆模态试验以及发电机侧部装卸试验验证，结果表明：该车体结构符合EN 12663-1:2024-02标准中规定的P-Ⅰ载荷和对应模态要求，满足发电机组侧部大开窗安装、拆卸的可靠性及发电车顶层指标要求。该车体结构不仅实现了发电机组侧部的高效安装、拆卸、维修作业，还可满足高温潮湿区域柴油发电机组高负荷供风散热需求。
Abstract：A novel power car body structure was developed to adapt to the operational environment, operational habits, line conditions, and top-level technical requirements of power generation units in South Asia. The structure,primarily constructed from ferritic stainless steel(1.4003) through welding, features a large-opening side window design and a sliding transverse beam structure for the power generation unit's base frame. Key innovations include an extended side roof beam framework between internal partition walls, a safety railing system for the power unit corridor,a quick-removable modular louver system for large-opening side windows, and expanded side roof ventilation windows.Validation through structural simulation, static strength testing, modal analysis, prepared vehicle modal testing, and generator-side loading/unloading experiments demonstrated compliance with the P-Ⅰ load and corresponding modal requirements specified in EN 12663-1:2024-02. The design achieves reliable large-window installation/removal operations for power generation units while meeting high-load air cooling demands for diesel generators in high-temperature and high-humidity regions.
