The invention relates to a spiral curved surface energy absorption device which comprises a bottom surface regular polygon and spiral curved surface single blades, the spiral curved surface single blades are arrayed circumferentially along the edge of the bottom surface regular polygon to obtain the spiral curved surface energy absorption device, and the bottom surface regular polygon comprises but not limited to a regular hexagon, an octagon and the like. The spiral curved surface energy absorption device can be axially provided with a certain taper, the taper angle is smaller than or equal to 5 degrees, the spiral angle of the spiral curved surface single blade is larger than or equal to 250 degrees, and the spiral curved surface single blade is thinner at the edge and thicker at the center. The spiral curved surface energy absorption device provided by the invention is mainly used in a vehicle, so that a large amount of collision energy can be dissipated when a vehicle is collided, the damage to a vehicle body is reduced, and the safety of passengers is protected.
本发明涉及一种螺旋曲面吸能装置,包括底面正多边形和螺旋曲面单叶,所述螺旋曲面单叶沿底面正多边形的边进行圆周阵列得到螺旋曲面吸能装置,所述底面正多边形包括但不限于正六边形、八边形等,所述螺旋曲面吸能装置轴向可以设置一定的锥度,锥角应小于等于5°,所述螺旋曲面单叶的螺旋角度大于等于250°,所述螺旋曲面单叶的厚度在棱边处较薄、在中心处较厚。本发明提供的螺旋曲面吸能装置主要用于交通工具中,使车辆发生撞击时能够大量耗散撞击能量,减少对车身的损害,保护乘员安全。
