Based on ANSYS static analysis method, displacement constraint method and fiber are adopted. The cable tension temperature compensation method is used to model the distance of the insulator of the mast base. In this paper, the stiffness matrix distortion and analysis of the moving structure in static analysis are solved. The problem of divergence is analyzed by using statics analysis to simulate the long-distance displacement of the mast base insulator. The dynamic analysis process provides theoretical basis for the implementation of the project.
