Numerical Simulation of Vehicle Crash into Reinforced Concrete Guardrail

Abstract:

On the base of the characteristic analysis in the process with the car crash into guardrail in our country, the paper major in analysis for contact stress and damage of steel concrete, car is solid model and guardrail is elastic-plastic model. Through ABAQUS element software, the paper simulate the dynamic response to the car crash into Reinforced concrete guardrail with different angles and velocities. The incident Angle unchanged, with greater speed is produced the bigger contact stress, in a very short period of time to a peak and quickly decreases. At the same speed, Angle increases, at the same time the damaged region increased. The results show that use the element ABAQUS software to simulate Car guardrail collision is feasible and the speed of cars and collision Angle have greatly influenced the safety performance of the cars and guardrails.
