摘要

海底电缆在装载、运输、敷设和运行过程中

受外界多种因素的影响时常会发生扭转

利用建模仿真的方法不仅可以克服实体试验操作困难的难题

还可获得实体试验难以提取的数据。文章利用ANSYS软件建立海底电缆扭转的有限元模型

进行了单元类型的选择、各层材料属性及参数的确定和网格划分方式的选择

并且分析、控制了影响计算时间和精度的因素

最后对海底电缆施加扭转载荷

仿真扭转发生过程

获取铜导体和光单元的应力及应变数据

为分析海底电缆扭转的力学特性提供了一种可行方案。

Abstract

In the process of loading transportation

installation and operation

the submarine cable is usually suffered from twist problem due to many external factors.The method of modeling and simulation can not only overcome the difficult problems in the entity experimental operation

but also obtain the stress and strain which is difficult to obtain in the entity experiment.In this paper

the finite element model of submarine cable torsion is first built.Then we select the unit type

material properties and parameters of each layer.Next

we analyze the factors that will influence the computation time and simulation precision.Finally

the constraint and speed loads are imposed to the model

which simulate the stretching twist process to obtain the stress and strain data.The modeling method in this paper provides a feasible solution to analyze the mechanical characteristics of submarine cable twist.
