海上漂浮输油软管拉伸特性的理论与试验分析

Theoretical and experimental analysis on tensile property of offshore floating oil hose

海上漂浮输油软管为复合型管,自内而外由不同形式与材料特性的结构层组成,经硫化处理使各层融合为一个整体。基于管体的分层假定、粘合假定、平断面假定、均匀性假定以及对橡胶材料和尼龙帘线加强橡胶部分的简化处理,运用分层分析方法,使用ABAQUS有限元分析软件对研发中的软管进行整体拉伸特性分析。将有限元计算结果与静态拉伸试验结果进行比较,虽然相对误差约20%,但在一定程度上反映了软管结构的拉伸特点,对于软管结构设计阶段的拉伸特性估算及结构优化具有重要的指导意义。(表1,图8,参13)

An offshore floating oil hose is a composite tube made of structural layers in different forms and with material properties from inside to outside. The layers are integrated as a whole after sulfidizing so that they are free of cracking and relative sliding during normal use. Based on assumption of layering, bonding, plane section and uniformity for the tube and simplified treatment of rubber materials and reinforcing rubber portion of nylon cords, ABAQUS finite element analysis software is used to conduct an analysis of overall tensile properties for the hose under research and development with the stratified analysis method. Finite element calculation results are compared with static tensile test results. Although relative error between them is about 20%, it reflects tensile properties of the hose structure to a certain extent and is of significant guiding significance for tensile properties estimate and structural optimization during the hose structure design. （1 Table, 8 Figures, 13 References）
