In this paper

three structure schemes of capacitor packaging box at the action of inertia and centrifugal force are compared and studied firstly through ANSYS software

such mechanical characteristics of each element and the complete device as mechanical strength and rigidity is obtained and the strength verification of corresponding stress value of the 4th strength theory is made. Secondly

the simulation analysis of the capacitor packaging box is made by ANSYS and its inherent frequency is obtained.Finally

the finite element calculation of the capacitor packaging model is made by way of inputting acceleration spectrum input from three directions and by the use of response spectrum method

and each structure of the capacitor packaging box is also verified. The most optimized design scheme is selected with such comprehensive considerations as economy

self oscillation frequency

the calculation and verification result.
