高速公路汽车与护栏碰撞的简化计算方法──柔性梁法

A Simple Simulation Method for Highway Vehicle-Barrier Crash──Flexible Beam Method

本文在实车碰撞实验的基础上，提出了汽车与护栏碰撞的简化计算方法──柔性梁法。该方法通过质点（车）在梁－柱结构（横梁为柔性，立柱为刚塑性或弹塑性）上滚动，来模拟汽车与护栏的动力碰撞过程，可得到车辆碰撞过程的运动轨迹及护栏位移。

On the basis of full scale vehicle crash tests, a simple vehicle crash simulation method──flexible beam method is developed. The method simulates the vehicle crash procedure by assuming the mass (vehicle) rolling on the beam-post system (beams be flexible, posts be stiff-plastic or elasto-plastici), and gives the vehicle trajectory and the barrier displacement.
