摘　　要：鉴于交通事故的频繁发生,防护栏的性能对车辆和行人的安全有着直接的影响。本文以小型客车与波形防护栏的碰撞为例,运用碰撞分析理论,并结合HyperMesh和LS-DYNA碰撞分析软件,建立“小型客车-波形防护栏”的碰撞仿真模型,根据JT-T281-2007公路波形梁钢护栏国家标准仿真分析得出波形防护栏的碰撞特性。该分析对波形防护栏的结构优化提供了一定的推荐价值。Given the frequent occurrence of traffic accidents,the performance of protective barriers has a direct impact on the safety of vehicles and pedestrians.This article takes the collision between a small passenger car and a corrugated guardrail as an example,applies collision analysis theory,and combines HyperMesh and LS-DYNA collision analysis software to establish a collision simulation model of"small passenger car-corrugated guardrail".Based on the JT-T281-2007 national standard for corrugated beam steel guardrails,the collision characteristics of the corrugated guardrail are analyzed through simulation.This analysis provides certain recommendations for the structural optimization of corrugated guardrails.
