The invention provides a high-speed subway head car body structure which comprises an underframe, a car roof, side walls, end walls, a cab framework and a cowcatcher, an underframe end beam is arranged at the end of the underframe, two anti-creeper devices are symmetrically arranged on the outer side of the underframe end beam with respect to the longitudinal center of the car, and the high-speed subway head car body structure is characterized in that a two-stage energy absorption structure is arranged at the end of the underframe; the cab framework is reinforced through design; a one-position end wall framework is arranged behind the cab framework; and a drawer type energy absorption unit is arranged on the cowcatcher. According to the high-speed subway head car body structure, through the arrangement of the two-stage energy absorption structure and the reinforcing design of the cab framework, the collision resistance of the structure is remarkably improved, the passive safety performance meets the requirements of high-speed-grade urban subway vehicles, the collision requirements of trucks on the same line, road vehicles, barriers at the level crossing and the like are met, and a brand-new efficient and safe subway car body structure is provided for subsequent urban subway operation.
本发明提供一种高速度地铁头车车体结构,包括底架、车顶、侧墙、端墙、司机室骨架和排障器,底架端部设有底架端梁,底架端梁外侧以车辆纵向中心对称设两个防爬器,其特征在于,所述底架的端部设有两级吸能结构;司机室骨架加强设计;司机室骨架后方设置一位端端墙骨架;排障器上设置抽屉式吸能单元。本发明的高速度地铁头车车体结构,通过设置两级吸能结构以及对司机室骨架的加强设计,其耐撞性能得到显著提高和改善,被动安全性能满足高速度等级城市地铁车辆要求,并满足同相同线路货车、公路车辆及平交路口障碍物等碰撞要求,为后续城市地体运营提供了全新的高效安全的地铁车体结构。
