Title: Dynamic Simulation Analysis Based on LS-DYNA about Impact Force on Bridge Pier Caused by Vehicle
Abstract: A vehicle dashing against a bridge pier can often be seen at an overpass bridge.For the purpose of exploring the changes of the impact force under different vehicle loads and from different impact angles,the LS-DYNA was employed to simulate the process of a vehicle dashing against a bridge pier,and the standard vehicle model and round-ended pier model were adopted.And by using three kinds of vehicle speeds with different vehicle loads and after calculation,the changes of impact forces with both the changes of vehicle loads and impact angles were ascertained,and the change rule of impact forces under different vehicle loads was researched.The results show that the peak and duration time of impact force curve are influenced by vehicle loads and by impact angles to a certain degree,and the maximum impact force exceeds the provision stipulated in relevant standard.
