Simulation of High-impact Grade Collision Test for New Bridge Safety Barrier
In view of frequent accidents and high casualties caused by vehicle collision with bridge guardrail,a study on new bridge safety barrier collision was carried out.The effect of the safety barrier of new bridge in high-impact grade crash test is simulated,and the safety factors affecting the deformation of the vehicle body,as well as the collision point,collision angle,collision speed and so on are analyzed.The results show that the most ener-gy is absorbed and the maximum deformation exists in the collision test.New bridges need paying enough atten-tion to the optimization of material and structure to improve the level of energy absorption.
