Simulation analysis of combined crash guardrail based on display dynamics
In this paper,a combined guardrail anti-collision system is proposed.The finite element software AnsysLS-DYNA is used to simulate the vehicle collision.HyperView and LS-PrePost are used to post-process the simulation and compare with the experimental data,which verifies the correctness and feasibility of the finite element simulation analysis.Simulated collision analysis of the guardrail system of medium-sized passenger cars under four combined working conditions shows that the guardrail can effectively guide vehicles into lanes and prevent vehicles from driving out,overturning and falling off bridges,which shows superior anti-collision performance.
