提高阻挡大型机动车辆路障效率的研究

A Study of Improving the Efficiency of Blocking Large Motor Vehicle

随着当今世界各国对安全的重视和汽车炸弹恐怖袭击的层出不断,防恐机动车阻挡路障的研究和应用成为重要课题。本文主要针对阻挡大型高速货车类车辆的路障进行了试验研究,利用LS-DAYNA建立了和试验结果吻合的有限元模型。参考美国DOS(Department of State)标准关于机动车阻挡路障的要求,通过模拟计算方法研究了如何提高对大型高速车辆的阻挡效率、减少车辆穿过路障距离的方案。模拟和试验表明,所提方案可以有效地阻挡大型车辆,对提高我国相关产品的性能并使之与国际标准接轨有重要指导作用。

With the world paying more attention to the safety and more and more vehicle-bomb,the study of blocking device against intrusive vehicle becomes an important task.In this paper,experiment were done to study the blocking device for large and high-velocity motor vehicle,and the finite element model developed by LS-DYNA was correlated with the experiment.This paper also consults the requirement of ANTI-RAM VEHICLE BARRIERS of America DOS(Department of State).Studying the method with computer simulation for how to improve the efficiency of blocking large and high-velocity motor vehicle and how to cut down the distance the motor vehicle intruding.it is important for improving the blocking device in our country and make them to reach the international criterion.
