船舶与高桩码头碰撞过程的数值模拟

基于ANSYS/LS-DYNA软件,模拟5 000吨级件杂货船分别以2 m/s和5 m/s两种撞击速度与江阴港3万吨泊位高桩码头的碰撞过程。得到并分析了船与高桩码头之间碰撞的能量变化和作用力,与船桥碰撞规范结果进行比较,得出了一般规律和特点,从而为同类码头的设计、维护等提供理论上的支持及工程上的应用指导。

Numerical simulation for collision between ship and high-piled wharf

The software of ANSYS/LS-DYNA is used to simulate the process of collision between a 5 000ton break-bulk cargo ship and the 30 000 ton high-piled wharf of Jiangyin port with the speed of 2 m/s and 5 m/s. This article analyzes the forces and change of energy in the process of collision. Comparing with the result of specifications,general rules and characteristics are obtained, which provide theoretical supports and an engineering guidance during the design and maintenance of similar piers.
