摘要
运用结构优化的方法,对防撞梁进行轻量化设计并分析防撞梁的刚度、模态、托钩强度及高速刚性墙碰撞等工况性能。结果表明:铝合金防撞梁的轻量化及安全性能较高强度钢均有明显改善,且铝合金防撞梁吸能量大,加速度峰值小,在满足被动安全性与行人保护安全性要求的同时,可实现轻量化。
Lightweight design of the anti-collision beam was investigated by structural optimization method.In addition,a series of performance,such as stiffness,mode,hook strength and high speed rigid wall impact,was also analyzed by this method.The results showed that the lightweight and safety capability of aluminum alloy anti-collision beam had improved significantly.Besides,the aluminum alloy anti-collision beam possessed greater energy absorption and smaller acceleration peak value,which could meet the requirements of passive safety and pedestrian protection safety,and simultaneously realized lightweight.
