对标准的路基压实土中圆形护栏立柱与土基的相互作用进行了模拟,在此基础上,基于非线性有限元软件LS-DYNA建立了波形梁护栏的有限元模型。在相同的碰撞条件下,对混凝土基础中和土基中护栏的碰撞安全性进行了仿真研究。结果表明,车与土基中护栏碰撞时对乘员造成的伤害值小于车与混凝土基础中护栏碰撞所造成的伤害值。
The interaction between the circular guardrail column and the soil foundation in the standard subgrade compaction soil was simulated. Based on this, the finite element model of the guardrail of the corrugated beam was established based on the nonlinear finite element software LS-DYNA. Under the same collision conditions, the collision safety between the concrete foundation and the guardrail in the soil foundation was simulated. The results show that the damage value of the occupant caused by the collision between the car and the soil barrier in the foundation is less than the damage caused by the collision of the car and the guardrail in the concrete foundation.
