Temperature Field Simulation of Cable Joints Based on FEM

doi:10.3969/j.issn.1000-7229.2016.02.021

Abstract

Abstract:

In order to simplify the calculation, generally, the model of cable joints is established with its axial symmetry during the temperature field simulation. But this model is different from the actual laying situation, as a result, the simulation is not accurate. We simulate the temperature fields of the cables under the axial symmetric model and the actual laying conditions respectively with using finite element software Ansys. Through the comparison and analysis, it can be found that a certain radius of the annular soil can be used to simulate the actual soil conditions. The radius is applied to the temperature field simulation of cable joints. Based on the proposed method of using a certain radius of the annular soil to simulate the actual cable laying soil conditions, we can make the temperature field simulation of cable joints more accurate under the axial symmetry model.

Key words: cable joint, temperature field simulation, temperature difference, finite element method （FEM）
