The invention relates to the technical field of anti-collision beam side collision crushing resistance, and discloses an aluminum alloy automobile anti-collision beam side collision crushing resistance method which comprises the following steps: step 1, optimizing the section design of an anti-collision beam, and adopting an asymmetric multi-cavity section structure to enable collision force to be transmitted and dispersed among different cavities; and secondly, shape memory alloy is introduced, the shape memory alloy is embedded in the anti-collision beam, and the anti-collision beam can automatically recover to the preset shape after being subjected to collision force. Through the combination of the asymmetric multi-cavity section design and the high-strength aluminum alloy material, the collision force can be uniformly dispersed among the multiple cavities, the plastic deformation energy absorption amount is improved, the impact force transmitted by a vehicle body is effectively reduced, and the collision force can be effectively reduced through the cooperative work of the adjustable crumple guide groove and the intelligent sensor. And direction rotation and depth adjustment of the guide groove are adjusted in real time according to the collision angle range and speed, and precise control over the crumple path is achieved.

    本发明涉及防撞梁抗侧碰压溃技术领域,且公开了一种铝合金汽车防撞梁抗侧碰压溃方法,包括以下步骤:步骤一:优化防撞梁截面设计,采用非对称的多腔室截面结构,以使碰撞力在不同腔室之间传递和分散;步骤二:引入形状记忆合金,在防撞梁上嵌入形状记忆合金,使其在受到碰撞力后能够自动恢复到预设的形状。本发明通过非对称多腔室截面设计与高强度铝合金材料结合,碰撞力可在多个腔室间均匀分散,塑性变形能吸收量提高,有效降低车身传递的冲击力,并且通过可调节溃缩引导槽与智能传感器协同工作,根据碰撞角度范围内和速度实时调整引导槽方向旋转与深度调节,实现溃缩路径精准控制。
