【摘要】借助ANSYS/LS-DYNA非线性有限元软件,对一艘20000 t级油轮与某箱式吸能防护装置的正撞过程进行有限元数值模拟,演示并分析了防护装置的受撞过程,碰撞中力和能量的时间历程、结构的损伤情况和防撞装置的作用,并对防护装置的结构尺寸及结构形式进行了分析,最终对合理的防护装置结构提出了一些建议,旨在优化防撞装置.更多还原

【Abstract】 In this paper,a non-linear dynamics finite element software ANSYS/LS-DYNA was applied to simulate the process of positive impact between a DWT 20000t oil tanker and a bridge equipped with a protection device of absorbing energy.The process of collision,the structure damage,the energy absorption capacity,the role of the anti-device,and the size of the structure were investigated.Finally,some advices on the structural optimization for anti-device were proposed.更多还原
