Noise Source Identification of a Ring-Plate Cycloid Reducer Based on Coherence Analysis

الملخص EN

A ring-plate-type cycloid speed reducer is one of the most important reducers owing to its low volume, compactness, smooth and high performance, and high reliability.

The vibration and noise tests of the reducer prototype are completed using the HEAD acoustics multichannel noise test and analysis system.

The characteristics of the vibration and noise are obtained based on coherence analysis and the noise sources are identified.

The conclusions provide the bases for further noise research and control of the ring-plate-type cycloid reducer.
