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。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.
