车辆碰撞混凝土护栏的数值模拟与应用

Simulation and Application of Vehicle Crash to Concrete Barrier

合理简化车辆冲撞混凝土护栏过程 ,得到计算仿真模型并编制计算机程序 .通过计算结果与文献的比较 ,证明了方法的合理性 ,最后对护栏安全的多个影响因素进行分析 ,进而提出混凝土护栏设计的建议 .

With rational predigest of the crash process of vehicle to concrete barrier,a new model is developed.Compard with the test results the validity of the simulation is approved.At last some affecting factors to barrier safety are analyzed and useful suggestions to design are obtained.
