Abstract: This paper starts from the multi-body dynamics analysis of drum washing machine to calculate the critical speed, and compares with the natural frequency of subwasher which does not consider the gyroscope effect, drawing the conclusion: After considering the gyroscope effect, the critical speed of drum washing machine will be decreased, and based on the safety design, the gyroscope effect should be considered in the critical speed analysis of subwasher, and thus this paper provides a method for this analysis.
