| Abstract: | In order to provide basis for the anti collision design for variable cross section pier, according to the basic structure and working principle of the anti collision device with variable cross section, the finite element model of anti collision device and ship is established by using finite element software LS DYNA. The energy transform, the collision force and the degree of device damage in the head on collision process between a 5 000 t cargo ship and anti collision device of a Y type pier under three different conditions are simulated. The results show that the collision force increases with the increase of the penetration, and the collision force reaches the maximum when the penetration reaches maximum. |
