Study on Mechanism in Ship-Bridge Collision and Collision-Preventing Device

摘要

Basing on the nonlinear finite element theory and the finite element analysis program LS-DYNA, the 3D finite element calculation mode of ship and collision-preventing device of the pier are built. The ship-bridge collision characteristic, the energy absorption trait and damage of the collision-preventing device and ship structure are discussed, meanwhile, some instructive conclusions are also concluded in this paper.
