Abstract

Based on the theory of finite element dynamics, the dynamic performance of the power regulator inverter is studied in this paper. The vibration simulation model of the inverter is established. According to the national standard for vibration environment, the vibration load is applied to the model, and the vibration response characteristics of the cabinet under excitation are obtained. In this paper, through studying the simplification of the inverter model and the finite element mesh division, a good finite element mesh model of inverter is generated. And then the natural frequencies and modes of the inverter are obtained based on modal analysis. Finally, the frequency response range of inverter cabinet from the 0~120Hz excitation of displacement and stress response are gotten through harmonic response analysis. Through vibration simulation analysis, the maximum impact on the structure in the frequency range of inverter can be found, and can be matched with modal analysis results.
