Transient Finite Element Simulation Analysis on Dolphin Structural under Ship Collision

Abstract:

Taking a certain dolphin structure of the ship lock in Jiangsu as an example, the finite analysis software ABAQUS was used to establish the 3D finite element model of ship, dolphin and foundation, and the process of collision was simulated for the transient dynamic analysis, obtained the collision force-time curve and the stress and strain of the dolphin, calculated ship collision force and compared with the norms used both in China and other countries. The results show that the maximum compressive stress is on the contact surface, the tensile stress is both on dolphin floor and back surface of the dolphin, and the maximum tensile stress is on the front teeth of dolphin floor; the ship collision force of finite element simulation is between Chinese norms and European norms. The results provide reference for the design of future dolphins.
