The invention discloses a composite step-by-step energy absorption structure of a railway vehicle, which comprises a front-end cross beam, a middle longitudinal beam, side beams, a front-end small cross beam, a rear-end small cross beam and a rear-end cross beam, wherein the front-end cross beam and the rear-end cross beam are arranged in parallel; two ends of the front-end cross beam are respectively connected with the side beams; the other ends of the two side beams are connected with the two ends of the rear-end cross beam respectively; one end of the middle longitudinal beam is connected with the middle of the front-end cross beam; the other end of the middle longitudinal beam is connected with the middle of the rear-end cross beam; the front-end small cross beam and the rear-end smallcross beam are both connected with the middle longitudinal beam; the rear-end small cross beam is located behind the front-end small cross beam; a second-stage energy absorption pipe is arranged between the front-end small cross beam and the rear-end small cross beam; a third-stage energy absorption pipe is arranged between the rear-end small cross beam and the rear-end cross beam; and honeycombaluminum is arranged in the third-stage energy absorption pipe. The composite step-by-step energy absorption structure can effectively reduce the impact force of the railway vehicle during initial collision, guarantees the stability of the deceleration process during collision of the railway vehicle, and is large in overall energy absorption capacity and good in unbalance loading resistance.

    本发明公开了一种轨道车辆的复合式逐级吸能结构,包括前端横梁、中间纵梁、边梁、前端小横梁、后端小横梁和后端横梁,前端横梁与后端横梁平行设置,前端横梁两端分别连接一边梁,两根边梁的另一端分别与后端横梁两端相连接,中间纵梁一端与前端横梁中部连接,中间纵梁另一端与后端横梁中部连接,前端小横梁和后端小横梁均与中间纵梁连接,后端小横梁位于前端小横梁后方,前端小横梁和后端小横梁之间设有第二级吸能管,后端小横梁与后端横梁之间设第三级吸能管,第三级吸能管内装设蜂窝铝。该复合式逐级吸能结构能有效降低轨道车辆在初始撞击时的冲击力,保证轨道车辆碰撞时减速过程的平稳性,整体吸能量大、抗偏载性好。
