以往用于独立桩(树、电线杆、桥墩等路面固定物)抗撞结构的优化设计方法,只能解决独立桩抗撞结构或车辆单方面的安全性优化设计问题,不能兼顾车辆与被撞物体的安全性优化设计.提出了一种独立桩抗撞结构的碰撞相容性优化方法,该方法以车-车碰撞相容性设计方法为参考,将独立桩抗撞结构视为“对方车辆”,将“独立桩”视为“对方车辆中的乘员”展开碰撞相容性研究,确定了独立桩抗撞结构的前端几何形状.然后,根据独立桩抗撞结构设计的轻量化要求,在独立桩抗撞结构的刚度设计中运用最大吸能原则的耐撞性拓扑优化设计方法,获取传力路径最佳的独立桩抗撞结构拓扑构型,解决独立桩抗撞结构与车辆的刚度匹配...

Previous optimization design methods of independent pile anti-collision structure (such as trees, poles, piers and other road fixed objects) are capable of settling the safety optimization problem of independent pile or vehicle unilaterally, however, the safety performance optimization design for the vehicle and the object impacted can't be solved simultaneously. A crash compatibility optimization method of independent pile anti-collision structure is proposed. Taking crash compatibility design method of vehicle-vehicle collision as a reference...
