【Abstract】 Based on the nonlinear finite element theory and the finite element analysis program LS-DYNA, the 3D finite element calculation model of ship and pier collision-preventing device is established. The ship-bridge collision characteristic, the energy absorption feature and damage of the collision-preventing device and ship structure are discussed, meanwhile, some instructive conclusions are also concluded in this paper.更多还原
