摘要
海底电缆中的钢丝铠装层结构复杂,呈多变的空间形状,建立精确的铠装层模型对研究光电复合海底电缆力学性能至关重要,而目前仍存在应力、应变、位移等性能不清等诸多难题。为解决上述问题,首次提出了电缆铠装层的精确建模方法与ANSYS有限元分析软件相结合,对光电复合海底电缆进行了整体建模,并构建了一种典型的单内铠光电复合海底电缆,采用拉伸试验仿真与实物测试结果比较,证明了铠装层建模方法的可行性与准确性,为降低实际试验所需的高昂物力提供了一种有效解决方法。
The steel wire armored layer of submarine cable is complex and kake on a changeable space shape. It is important to build accurate models for researching the mechanical performance of the cable, but there are still many difficulties. The method of building precise model of the steel wire armored layer and ANSYS software and its ADPL language were combined for the first time, the submarine cable model was built and a typical single armored photoelectric composite submarine cable was built finally. The results of simulated tensile test and physical test were compared. Comparation results certified the feasibility and accuracy of the modeling method proposed in this paper. The method provide a solution to reduce the expensive cost required for the practical test.
