초록

In guard rail crashes, the development of guard rail structure to ensure the maintenance of safety for passengers is very important. So, this paper focuses on understanding the possibility of efficient structural development considering crash strength of guard rail through computer simulation using the commercial code, LS-DYNA3D at the initial stage of guard rail development. For this study, guard rail structure was modeled using shell elements to represent major structural members and passenger car was modeled using plate elements of simple shape to do not have the drawing, and impact boundary conditions required by regulation was applied. In order to confirm the validity of the computational results, they were compared with the test results.
