| Abstract: | In this paper,a non-linear dynamics finite element software ANSYS/LS-DYNA was applied to simulate the process of positive impact between a DWT 20000t oil tanker and a bridge equipped with a protection device of absorbing energy.The process of collision,the structure damage,the energy absorption capacity,the role of the anti-device,and the size of the structure were investigated.Finally,some advices on the structural optimization for anti-device were proposed. |
