Precision spectrum analysis of the grinding wheel unbalanced signal

摘要

This article studied the signal reconstruction algorithm of unbalanced vibration signal under strong disturbance background based on weight load balancing principle. Using the precise spectrum analysis method, we can carry out signal reconstruction and obtain the true value of grinding wheel unbalance quantity. Given a kind of unbalanced signal extraction and reconstruction method based on the wavelet packet translation, the ability and validity of extracting grinding wheel unbalanced vibration signal between FIR band-pass filter and the wavelet packet algorithm are studied and compared, and the difficult question of accurate extraction of unbalanced vibration signal can be solved.
