Stress Analysis of Submarine Cable Tension and Torsion Test Device Based on Finite Element Method

In order to ensure that the tension and torsion test system can complete the normal test of submarine cable torsion, it is very important to analyze the maximum torque that the system can withstand. In this paper, the finite element simulation software ANSYS is used to model the submarine cable tension and torsion test system. The torque of 1kNm, 5kNm and 10kNm is applied to the model and solved. The main force position of the torsion device was evaluated by analyzing the changes of displacement, stress and strain after the model was twisted. The results show that after applying the maximum allowable torque of 10kNm to the submarine cable tension and torsion test system, the system is not damaged, and the displacement, stress and strain changes are consistent with the actual situation, and the work of torsion testing of the submarine cable can be completed. This paper provides a method and data reference for the evaluation of the operating parameters of the submarine cable tension and torsion experimental system.
