The invention discloses a perforated multi-pipe combined type energy absorption device which comprises a rear end plate and a plurality of energy absorption square pipes. The energy absorption squarepipes are installed on the rear end plate, a plurality of through holes are formed in the side walls of at least part of the energy absorption square pipes, and the distances between the longitudinally adjacent through holes in the different energy absorption square pipes are different. According to the perforated multi-pipe combined type energy absorption device, the impact force peak value in the collision process of the energy absorption device can be greatly reduced, impact force fluctuation in the collision process of the energy absorption device is effectively relieved, and energy absorption of the energy absorption device in the collision process can be guaranteed.

    本发明公开了一种开孔多管组合式吸能装置,包括:后端板;多根吸能方管,吸能方管安装在后端板上,至少部分的吸能方管的侧壁上开设有多个通孔,且不同的吸能方管上纵向相邻的通孔的孔间距不相同。本发明的开孔多管组合式吸能装置既能够大幅度地降低吸能装置碰撞过程中的撞击力峰值,有效地缓解吸能装置碰撞过程中的撞击力波动,又能够保证吸能装置在碰撞过程中的能量吸收。
