Abstract: Based on ANSYS /LS-DYNA，the crash between vehicle and semi-rigid guardrails is simulated． And the differences of vehicle track，occupant safety and guardrail deformation between semi-rigid double wave guardrails and double semi-rigid guardrails are compared and analyzed． The results show that the semi-rigid double wave guardrail is likely to cause drill accidents and saddle accidents when crash happens; while the double semi-rigid guardrail can prevent those kinds of accidents efficiently，which can also meet the safety requirements of occupant and vehicle．

Key words: semi-rigid double-wave guardrail, double-bar semi-rigid guardrail, height of guardrail, impact simulation

摘要： 基于ANSYS /LS-DYNA 仿真平台，对车辆与半刚性护栏碰撞进行了数值模拟计算，对比分析了半刚性双波护 栏和双条半刚性护栏在车辆运行轨迹、乘员安全性及护栏变形量3 个方面的差异。研究结果表明: 半刚性双波护栏 容易造成某些车辆与其碰撞时发生下钻事故和骑跨事故; 双条半刚性护栏可以有效防止此类事故的发生，并达到了 车内乘员和车辆行驶的安全要求。
