摘要:
海上漂浮输油软管为复杂的组合截面柔性结构，制造工艺复杂，造价高昂。基于有限元方法，采用ABAQUS 软件，分析计算了5 层粘合型海上输油漂浮软管在管内无压及带压工况下的轴向拉伸载荷与拉伸率、曲率与弯矩之间的非线性关系及产生机理。通过模型计算，得到了管道各层的应力分布特点，结果表明，因其非对称的结构特点，粘合型管道仍然存在非线性的等效截面刚度特性。分析了螺旋钢筋布置角度、螺旋钢筋直径、帘线-橡胶复合材料层帘线布置角度等结构设计参数对轴向载荷作用下管道拉伸率的影响，相关研究成果可为管道设计提供参考。
Abstract:
Offshore floating hose is a combination section flexible structure with a complex manufacturing process, high performance and high cost.Based on the finite element method, by the use of ABAQUS software, non-linear relationships between axial tensile load and stretch rate and between curvature and bending moment of five-layer adhesive offshore oil floating hose under pressure and pressure-free conditions and formation mechanisms are analyzed and calculated. By analyzing the model, stress distribution characteristics for different layers of hose are obtained, and it is pointed out that the adhesive hose still has the non-linear equivalent section stiffness characteristics due to the nonsymmetrical structure feature. Influences of spiral reinforcement layout angle, spiral reinforcement diameter, cord thread layout angle of cord thread-rubber composite layers, and other structural design parameters on the hose stretch rate under the axial load are analyzed. It is considered that the relevant research results can provide a reference to the design of oil hose.
