| Abstract: | The dynamic model of vehicle reinforced concrete guardrail system is set up in the light of the deformation of both vehicle and guardrail; and the simulation program coded on microcomputer is used to solve the dynamic equation and simulate the whole process of vehicle impacting on reinforced concrete guardrail.The vehicle response such as displacement,acceleration,etc,and the vehicle forces acting on the guardrail are also presented.This method has been applied to design traffic barriers in Tieling,Liaoning Province. |
