摘    要:深水S型铺管涉及三维空间的大变形和接触分析,由于收敛速度慢而导致求解困难.为克服这个问题,本文提出了一种子结构方法;通过凝聚托管架内部结点自由度,铺管问题可在二维空间表述和求解.本文方法具有快速收敛的特点,可对铺管问题进行广泛的参数研究.

关 键 词:管道  托管架  子结构  托辊

Abstract:Deep-water S-Lay of pipelines requires large deformation and contact analysis in three-dimensional space. It is difficult to be solved due to slow convergence rate. To overcome this problem, a substructure method is presented in this paper. By condensing the degrees of freedom of internal nodes of the stinger, the pipelay problem can be formulated and solved in two-dimensional space. This method has the advantage of fast convergence rate and can be used to carry out extensive parametric studies for pipelay problem.
Keywords:pipelines  stinger  substructure  Roller
