船舶撞击靠船墩结构的瞬态动力分析
Transient dynamic analysis of dolphin structure under ship collision
摘要
Abstract
Based on the dolphin structure of the ship lock in Jiangsu,the finite analysis soft-ware ABAQUS integral algorithm was used to establish the 3D finite element model of ship,dolphin and foundation,the process of collision was simulated to obtain the impact force-time curve and the stress and strain of the dolphin in two different working conditions of high and low water level.The results show that the maximum compressive stress is on the contact surface,the tensile stress is both in dolphin floor and back surface of the dol-phin,and the maximum tensile stress is in the front teeth of dolphin floor.The stress of the dolphin in low water level is greater and the dolphin is more dangerous.关键词
