Analysis of tension-bending response of flexible risers considering interlayer anisotropic friction
摘要
Abstract
Flexible risers are critical components in offshore oil and gas exploitation.To clarify the influence of interlayer anisotropic friction on the bending structural behavior of unbonded flexible risers,a refined three-dimensional finite element model is developed,in which an anisotropic friction model is incorporated to character-ize the interlayer contact behavior between the tensile armor wires and the anti-wear layer.The effects of anisotro-pic friction on the bending stiffness,armor wire stress and relative sliding of the riser are investigated.The results show that the friction coefficient in the winding direction of the tensile armor wires has a significant effect on the bending stiffness of risers,as well as the magnitude and distribution of stress in the tensile armor wires.As this friction coefficient increases,the nonlinear characteristics of the bending response of risers become more pronounced,and higher armor wire stresses are induced under the same curvature.particular attention should be paid to the friction coefficient in the winding direction when designing and analyzing the structural performance of unbonded flexible risers.This study provides a method for the high-performance design of flexible riser structure.关键词
