摘要
对防撞护栏的设计方法和设计条件进行了系统性的论述。采用ANSYS/LS-DYNA3D软件,通过计算机仿真对车辆与梁柱式防撞护栏的碰撞过程进行分析,提出了改正这种梁柱式防撞护栏的措施,并对改正后的防撞护栏进行了碰撞分析,表明改正后的防撞护栏可以有效地将碰撞车辆导向车道。
The design methods & conditions of crash barrier are presented systemically in this paper.Through computer simulation,ANSYS/LS-DYNA3D,the crash process of vehicle and beam-column typed crash barrier is analyzed,and on this basis,the correction methods to this crash barrier are proposed and the crash analysis after the correction is finished.The results show that corrected crash barrier can guide the crash vehicle to the lane effectively.
