摘要
以ANSYS/LS-DYNA为软件平台,提出一种处理船舶与海洋平台碰撞的有限元建模分析方法,优于传统的分步多次计算方法,通过数值实验证明有相当的精度,能够满足研究需要。探讨碰撞中的应变率问题,并计算船舶以2 m/s碰撞导管架平台的动力响应。
A finite element analysis was carried out to process the problem of ship-jacket platform collision based on the software ANSYS/LS-DYNA. The numerical method surpasses the traditional method of multi-step and multi-calculation, proving enough accuracy to meet the research needs. The authors also discussed the effect of stain rate in ship--platform collision, and the dynamic response of ship-jacket platform collision at the speed of 2 m/s was calculated.
