3D printing metamaterial anti-collision guardrail
A 3D printing metamaterial anti-collision guardrail comprises guardrails, concrete columns and bolts, each guardrail comprises an inner-layer steel sheet, a sandwich layer and an outer-layer steel sheet, the inner-layer steel sheets and the outer-layer steel sheets are bonded to the two sides of the sandwich layer respectively, the multiple guardrails are connected through the bolts, and the concrete columns are arranged at the joints of the adjacent guardrails. The structure is small in rigidity and high in energy absorption efficiency, a vehicle can be buffered and decelerated during collision, impact damage to the vehicle is reduced, and meanwhile the vehicle is prevented from rushing out of a lane.
一种3D打印超材料防撞护栏，包括护栏、混凝土柱和螺栓，所述护栏包括内层钢片、夹芯层和外层钢片，所述内层钢片、所述外层钢片分别粘合于所述夹芯层的两侧，多个所述护栏通过所述螺栓连接，且相邻的所述护栏连接处设置有所述混凝土柱。本发明所述结构不仅刚度小，能量吸收效率高，而且碰撞时可以对车辆进行缓冲减速，减小车辆受到的冲击伤害，同时防止车辆冲出车道。
