SHOCK PULSE REPETITION FREQUENCY ESTIMATION BY PERIODIC WAVELET TRANSFORM

Abstract

The algorithm for shock pulse repetition frequency estimation based on periodic wavelet transform was proposed. The algorithm was applied to both synthesized and real vibration data. The applicability of the algorithm for vibration diagnostics of rotating machinery health by model defects was confirmed.
