| Abstract: | Based on the survey of a variety of road and bridge steel barrier posts and mechanical analysis, a new design of the buffer barrier post is presented in this paper, By the finite element analysis, the buffer barrier post has obvious advantages on the improving stiffness and saving amount of the materials comparing to the normal barrier post. Real vehicle crash test verifies the correctness of the conclusions of the finite element analysis |
