中文摘要：

针对目前高速公路广泛使用的W形护栏，在CAD数据模型的基础上采用有限元分析软件HyperWorks的前处理模块HyperMesh建立货车-护栏的有限元模型，在显示动力分析软件LS—DYNA环境下进行W形护栏与厢式货车的碰撞仿真计算，然后在HyperWorks的后处理模块HyperView和HyperGaph中分析计算结果，得到了W形护栏和厢式货车碰撞的主要特性：乘员安全性，车辆运行轨迹以及护栏的完整性。最后根据分析得到W形护栏碰撞厢式货车的相关特性，阐述W形护栏在结构等相关方面上存在的问题，并为护栏的设计人员提供理论参考。

英文摘要：

Widely used for highway w-shaped guardrail,ln the CAD data model, on the basis of finite element analysis software HyperWorks pretreatment module of HyperMesh build finite element model of the van -fence, in the display of dynamic analysis software ls-dyna environment w-shaped guardrail and van crash simulation calculation. And then in the post-processing module of HyperWorks HyperView and HyperGaph analysis and calculation results, obtained the w-shaped guardrail and main features of the collision of van： occupant safety, vehicle trajectory and the integrity af the fence. According to the analysis of collision characteristics of w-shaped guardrail, described w-shaped guardrail on the structure of existing problems and provide academic reference for designers.
