摘要
本文运用弹性杆理论建立了小应变、大挠度铺设过程中海底管道的静态分析力学模型。介绍了有限差分法在求解该大挠度、非线性、两点边值问题模型中的应用,并对如何模拟边界条件提出了一整套方法。讨论了环境和铺管系统主要参数对管道受力和变形的影响。
In this paper, the elastic rod theory is applied to establish a static analytical mechanical model for a small strain, large deflection marine pipeline during installation in ocean. This paper presents the application of difference methods in solving the large-deflection nonlinear and two-point boundary value problem model and a set of approaches to simulating the boundary conditions. This paper alos discusses the effects to the mechanical properties and deformation of the marine pipeline caused by the main environmental parameters and Laying pipelines system parameters.
