AI Technical Summary

Technical Problem

Existing methods for testing the performance of harmonic reducers have a high false alarm rate and are difficult to effectively distinguish between internal damage and external interference.

Method used

By acquiring acoustic emission signals and micro-vibration signals during the operation of the harmonic reducer, feature extraction is performed on each signal, and a multi-dimensional damage judgment index is constructed. The acoustic emission feature sequence and micro-vibration feature sequence are combined for collaborative judgment to distinguish between internal damage and external interference.

Benefits of technology

It significantly reduces the false alarm rate, improves detection accuracy, reduces system complexity, and effectively distinguishes between internal damage and external interference.

Abstract

The application discloses a kind of performance detection method and device of harmonic reducer, it is related to fault detection technical field, the performance detection method of harmonic reducer, comprising: obtaining acoustic emission signal and micro-vibration signal in the operation process of harmonic reducer, utilize the response difference of both in the response difference of different stages of damage evolution to carry out collaborative judgment, to distinguish internal damage and external interference, without carrying out feature fusion etc. Means, improve the detection accuracy while reducing the system complexity. By feature extraction to acoustic emission signal, obtain acoustic emission feature sequence;Micro-vibration signal is extracted to feature, and micro-vibration feature sequence is obtained;Based on acoustic emission feature sequence and micro-vibration feature sequence, construct multidimensional damage judgment index;According to multidimensional damage judgment index, determine the performance detection result of harmonic reducer. Utilize the feature difference of double signal response, realize the capture of harmonic reducer exception, significantly reduce the false positive rate.
