基于ANSYS/LS-DYNA船舶与高桩码头碰撞模拟

摘要

基于ANSYS/LS-DYNA应用软件,采用显式时间积分瞬态非线性有限元技术,对5000t级件杂货船分别在2m/s和5 m/s2种撞击速度的情况下,与3万t泊位高桩码头的碰撞过程进行数值模拟.获得了高桩码头上部结构的位移,以及接触区域应力应变的变化,分析了桩基在不同速度下的破坏情况和承载能力,得出了一般的规律和特点.%Based on ANSYS/LS-DYNA software, the explicit time integration for nonlinear transient finite element technology was used in this paper. The collision processes of multipurpose ship (5 000 DWT)with two speeds (2 m/s,5 m/s)and high-pile wharf (30 000 DWT)were numerically simulated. Then the superstructure displacement of high-pile wharf and the stress-strain of contact zone were obtained and analyzed. The damage situation and bearing capacity of pile foundation were also analyzed to get the general rules and characteristics.
