摘　　要：为研究三芯海缆在扭转条件下的受力情况和位移变化,以HYJQF41-F-26/353×500三芯光纤复合海底电缆为研究对象,基于有限元软件COMSOL构建三芯海缆的精准数值仿真模型。在确保力学结构准确性的前提下对三芯海缆仿真模型进行了优化,模拟三芯海缆在海洋条件下受到外力时发生的扭转行为,并分析钢丝铠装、线芯铜导体、光纤单元受到扭转时应力分布特征和位移变化情况。通过应力分布演化图,精确计算出应力的最大值和最小值。观察应力-位移的特征分布图,了解应力与位移变化的关系。To study the stress and displacement changes of a three core submarine cable under torsional conditions,this paper takes the HYJQF41-F-26/353×500 three core optical fiber composite submarine cable as the research object,and constructs an accurate numerical simulation model of the three core submarine cable based on the finite element software COMSOL.On the premise of ensuring the accuracy of the mechanical structure,optimize the simulation model of the three core submarine cable,simulate the torsional behavior of the three core submarine cable under external forces in marine conditions,and analyze the stress distribution characteristics and displacement changes of the steel wire armor、copper conductor core、,and optical fiber unit when subjected to torsion.Accurately calculate the maximum and minimum values of stress through the stress distribution evolution diagram.By observing the characteristic distribution map of stress displacement,we can understand the relationship between stress and displacement changes.
