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.
