Abstract

Abstract: At high speed, the outer drum vibrates because of eccentricity of clothes, which causes vibration and noise of the drum Washing machine. The natural frequency and vibration mode of the box are obtained through the modal analysis of the box shell. The structure of the box shell is optimized to improve the natural frequency of the box shell. Through the experimental verification, the maximum vibration of the box body is reduced by more than 66.8%.

Key words: Modal simulation, Vibration Testing, Washing machine, Optimal design
