【Abstract】 An explicit non-linear dynamics finite element software ANSYS/LS-DYNA was applied to simulate the process of collision between a cargo boat and a pier of Tianxingzhou Bridge equipped with a protective device.The structure damage in collision and the energy absorption characteristics of each component of the protective device were analyzed.Combining the calculation result,some reasonable suggestions for improvement were proposed in order to increase the crashworthiness of the anti-collision device.更多还原
