An Improved Time-Frequency Analysis Method for Instantaneous Frequency Estimation of Rolling Bearing

Instantaneous frequency estimation of rolling bearing is a key step in order tracking without tachometers, and time-frequency analysis method is an effective solution. In this paper, a new method applying the variational mode decomposition (VMD) in association with the synchroextracting transform (S...
