摘要
针对非金属非粘结软管在拉伸状态下的力学特性,采用ABAQUS对其进行有限元分析并充分考虑了对层与层之间的摩擦接触。研究表明,提高抗压层扁带的环向强度、抗拉层扁带的轴向拉伸强度及环向拉伸强度可以提高软管的抗拉性能;抗拉层螺旋缠绕角和抗拉层厚度对软管拉伸刚度的影响较大,而内外压、抗拉层扁带数量和摩擦系数对软管拉伸刚度的影响很小。
In order to study the mechanical property of un-bonded flexible fiber reinforced pipe （FFRP） under tension, a detailed finite-element analysis （FEA） of un-bonded FFRP was presented in ABAQUS considering the frictional contact between all layers. It was shown that the tensile property of the flexible pipe can be enhanced when the hoop strength of compression resistance armor layer, the tensile strength and hoop tensile strength of tension resistance armor layer are enhanced. The lay angle and the thickness of tension resistance armor layer have a great influence on the tension stiffness of the flexible pipe, while the influence of internal and external pressure, tendon number of tension resistance armor layer and friction coefficient is little.
