Under action of such dynamic loading as earthquake

wind load

etc.

the internal force is generated by each structure of capacitor tower due to its deformation and displacement. For assuring sufficient strength and rigidity of the complete tower structure of DC filter capacitor

the dynamic simulation and analysis on the mechanical properties of the tower must be performed. In this paper

different types of model of the capacitor tower structure are set up by the ANSYS finite element method

and then dynamic simulation calculation is made. The main geometry design parameters of the structure

especially the influence of abrupt layer at the upper structure on the structure stability

are compared and analyzed.At last

the optimum design suggestion the capacitor tower structure is proposed to provide evidence on the design and manufacture of the tower structure of capacitor.
