The invention discloses a method for reducing shock wave energy of a vehicle floor and a special anti-shock floor thereof, and belongs to the technical field of vehicle floors. The anti-impact floor comprises a U-shaped plate, an anti-explosion structure and a fastening device, the fastening device fixes a side plate of the U-shaped plate to the side wall of the vehicle, so that the middle position of the U-shaped plate is in a suspended state, and the anti-impact floor can bear larger-amplitude structural deformation; in addition, when the bottom of the vehicle is subjected to explosion impact, impact wave energy is transmitted through an air medium, and the impact load borne by the U-shaped plate can be effectively reduced; the bolt axial direction of the fastening device is perpendicular to the shock wave propagation direction and is far away from the middle maximum deformation area, so that the separation difficulty is increased, and secondary injury to people in the vehicle can be avoided; the explosion-proof structure of a corrugated structure is arranged below the U-shaped plate, and the U-shaped plate is designed to be of a sandwich structure, so that a large amount of impact kinetic energy can be absorbed, and the impact energy borne by the U-shaped plate is reduced. In addition, the invention has the advantages of simple manufacture, convenient replacement and the like.

    本发明公开了一种降低车辆底板冲击波能量的方法及其专用防冲击地板,属于车辆地板技术领域。防冲击地板包括U型板、防爆结构和紧固装置,紧固装置将U型板侧板固定在车辆侧壁上,使得U型板中间位置呈悬空状态,可以承受更大幅度的结构变形;另外,当车辆底部受到爆炸冲击时,冲击波能量通过空气介质传递,可以有效减少U型板受到的冲击载荷;紧固装置的螺栓轴向与冲击波传播方向垂直,且远离中间最大变形区域,使得脱离难度加大,从而可以避免对车内人员造成二次伤害;在U型板下方设置波纹状结构的防爆结构以及U型板设计为三明治结构,可以吸收大量冲击动能,减少U型板受到的冲击能量。另外,本发明还具有制造简单、替换方便等优点。
