Abstract: In order to test the effectiveness of the blocking effect of Class B corrugated beam guardrails on cars that are about to rush out of the road, a finite element model of cars and corrugated beam guardrails is established, and computer simulation software is used to complete the collision experiment of the corrugated beam guardrail, and the dynamic calculation software LS-DYNA, under this software environment, complete the large deformation calculation of the collision between the vehicle and the guardrail. After obtaining the test results, use Hyper View to extract the result file and observe the deformation of the guardrail and the ac-celeration curve of the vehicle. Finally, analyze and summarize the data of the collision experiment results.
