Highway Central Median Guardrail Collision Simulation Research And Application

This thesis entirely studied national & international problems of anti-collision guard rail and analyzed national the disadvantages of collision model. Incorporating computer simulation technology, the author gave the researching method of median barrier for anti-collision on the basis of ADAMS computer simulation. Firstly considering curbs, 3D automobile model, guard rail model, curb model , and collision model were established. Through simulation tests with curb, the real time data was obtained. Meanwhile, the author concluded that curb set is median strip has great influence on the safety of driving, analyzed the relationship between collision angle and safety, appraised the safety guard rail and finally offered the foundation of drawing up new standards.
