To explore a convenient and reliable installation method for power fault diagnosis devices while avoiding vibration and noise issues during operation. The finite element model of terminal was established. The vibration characteristics of terminal was analyzed under different working conditions. The causes of vibration and noise were found. The objective function was set to improve the lower order frequency. Combining with Kreisselmaier-Steinhauser equation, the variable density method was used to optimize the upper cover plate of the terminal. The optimal topology structure of the upper cover plate was obtained. The simulation results after optimization show that the lower order frequency of the upper cover plate is increased, which can avoid resonance phenomenon.

摘要

To explore a convenient and reliable installation method for power fault diagnosis devices while avoiding vibration and noise issues during operation. The finite element model of terminal was established. The vibration characteristics of terminal was analyzed under different working conditions. The causes of vibration and noise were found. The objective function was set to improve the lower order frequency. Combining with Kreisselmaier-Steinhauser equation, the variable density method was used to optimize the upper cover plate of the terminal. The optimal topology structure of the upper cover plate was obtained. The simulation results after optimization show that the lower order frequency of the upper cover plate is increased, which can avoid resonance phenomenon.
