The purpose of this paper is to examine the opportunity of non-linear dynamic impact simulation and to show the possibility of using finite element method (FEM) for developing new designs of safety barrier. Basic tasks of work are to determine a method that leads to creation of validated finite element (FE) model before performing the full scale crash and to perform non-linear dynamic impact simulation on this model in LS-DYNA. This method should help to improve accuracy of FE model that are used for non-linear dynamic impact simulation. Results of more accurate impact simulation will help to reduce necessary costs for developing new safety barrier. |
