Vibration Testing and Analysis of Mining Reducer by Haar Wavelet
Based on the Haar wavelet denoising method,the noise is filtered out from the vibration test signal of the reducer,and the fast Fourier transform is carried out on the time-domain signal after the noise reduction to analyse and diagnose the operation status of the reducer from both the time domain and the frequency domain.Taking a mining reducer as the research object,the described method is used to detect the damage of each original component in its maintenance link.
