Abstract:

In this study, the crash of a medium heavy vehicle onto a designed vehicle barrier is studied numerically. Structural integrity of the vehicle barrier is studied by nonlinear dynamic methods under the loading conditions which is defined in the standards. Nastran and Ls-Dyna which are commercial softwares are used to solve the problem. Outer geometry determination, allignment of the inner part and material properties of the vehicle barrier are studied linearly to yield design parameters. Best design parameters are determined to achieve the most structurally optimized vehicle barrier. Strain and stress values of the vehicle barrier are obtained by solving the partial differantial equations.
