Numerical simulation of crash test for bridge safety barrier

Original language description

The first part of this work deals with the creation of FE model, which the newly-designed safety barrier was used in, and focuses on application of an experimental modal analysis (EMA). After performing the EMA, the FE model is validated by comparing measured modal frequencies with calculated ones. Verification process was tested on steel bridge crash barriers. Therefore only steel crash barriers are discussed below. The second part describes processes that lead to the performance of non-linear dynamicimpact simulation on previously validated model. Dynamic impact simulation has been performed by using LS-DYNA explicit solver. Issues such as ensuring vehicle stability during impact and redirection, problem of proper accounting of friction effect and monitoring energy dissipation in whole system are described in this article.
