刚性护栏在事故碰撞中的冲击力计算

The Solution of Rigid Barrier's Impact Force in Collision

对刚性护栏在事故碰撞中的冲击力计算方法进行了讨论和简要的评论．对将汽车和护栏作为连续系统的动力模型作出了修正．采用该修正模型，研究了刚性护栏在汽车撞击作用下的动力响应，并分析和讨论了冲击角度、冲击速度、冲击质量，以及回弹刚度等因素对冲击力的影响．

This paper remarks and discusses briefly on the calculated methods of rigid barrier's wallop in collision. Revises the dynamic model of vehicle-rigid barrier continuous system. Studies the dynamic response of rigid barrier in vehicle's bumping using this revised model. Draws and analyzes the curves of impact-force by changing some parameters in the paper, and then obtains the correlatively results.
