本研究中的钢丝缠绕增强柔性管主要由多个各向异性钢丝缠绕增强层和多个各向同性橡胶层组成。基于三维各向异性弹性理论，给出了钢丝缠绕增强橡胶软管在内压作用下的应力和弹性变形的解析解。由于缠绕角度不同的相邻加强层半径不同，单个加强层表现出拉剪耦合效应。钢丝缠绕增强橡胶软管在内压作用下的静载试验结果与本文方法的计算值基本吻合。
Steel wire wound reinforced flexible pipe in this study mainly consists of multiple anisotropic steel wire wound reinforcement layers and multiple isotropic rubber layers. Based on 3D anisotropic elastic theory, the analytic solutions of stresses and elastic deformations of steel wire wound reinforced rubber flexible pipe under internal pressure are presented. As the adjacent reinforcement layers with wound angle have different radii, the single reinforcement layer shows the effect of tensile-shear coupling. Moreover, the static loading test results of steel wire wound reinforced rubber flexible pipe under internal pressure are basically coincided with the calculated values by present method.
