摘要
针对深水柔性管道铺设的一般过程,将铺设过程离散成若干典型工况,并通过非线性时域有限元法实现铺设过程的动态仿真分析。阐述仿真所涉及的基本方程、模型与基本单元、载荷工况与动态响应统计的具体处理技术。以水深1 000 m柔性管道的铺设为例,着重展示动态仿真技术在铺设设计中的应用。分析实例表明:通过非线性时域动态分析技术对深水柔性管道的铺设过程进行仿真是可行的,可以有效地为铺设设计提供指导。
The general process of flexible pipe-laying in deep water are divided into several typical cases,so that the nonlinear time domain finite element simulations can be performed. The detailed techniques are described including the involved governing equations, modeling and basic elements, the considerations on load conditions and statistics of dynamic responses. An example of flexible pipe-laying at a water depth of 1 000 m is taken to show the application of dynamic simulation in laying design. The results indicate that the nonlinear time domain dynamic analysis is feasible to perform the simulation on the deep water flexible pipe-laying. It can provide effective reference for pipe-laying design.
