摘　　要：针对高速公路涉及刚性护栏的交通事故频发,造成财产损失较大的情况,在CAD数据模型的基础上,采用有限元分析软件Hyper Works的前处理模块Hyper Mesh,建立了厢式货车-刚性护栏的有限元模型。在Ls-Dyna环境下,对厢式货车与刚性护栏进行碰撞仿真实验,并利用Hyper View及Hyper Gaph分析了厢式货车变形情况、运动轨迹及乘员安全情况。分析结果表明,刚性护栏起到了很好的导向和防御作用。Aiming at the current highway traffic accidents involving rigid guardrail and property damage, on the basis of tile CAD data model, the finite element model of rigid guardrail van is established hy using HyperWorks pretreatment module HyperMesh. And the collision analysis of rigid guardrail and van is made in the environment of Ls-Dyna, then van collision deformation, van trajectory and occupant safety are analyzed by HyperView and HyperGaph. The results show that the guidance and defense of rigid guardrail are effective.
