摘要
建立了深水分离器结构的实体数值模型,分析了分离器结构的多阶屈曲模态,并在此基础上,引入材料非线性本构关系和几何大变形理论,深入研究了结构非线性屈曲特性,其结果可为深水分离器结构设计和校核提供参考。
Subsea separator serves in the bottom of the sea with high outer pressure. Buckling instability is a key factor for subsea separator structure designing. This paper focus on the subsea separator structure nonlinear buckling characteristics. The simulation model of the subsea separator structure was established by element Solid 95. And buckling modes of the subsea separator structure were analyzed. On this basis, the nonlinear buckling characteristics were studied by introducing the material nonlinear constitutive relation and geometric large deformation theory, which laid technology foundation for deep water separator structure designing and checking.
