A TACHOLESS ORDER TRACKING METHOD BASED ON INVERSE SHORT TIME FOURIER TRANSFORM AND SINGULAR VALUE DECOMPOSITION FOR BEARING FAULT DIAGNOSIS

A Tacholess Order Tracking Method Based on Inverse Short Time Fourier Transform and Singular Value Decomposition for Bearing Fault Diagnosis

Order tracking has been widely used to diagnose failures of variable speed rotating machines.The performance of the TOT (Time-Frequency Domain Tacholess Order Tracking) methods is based Mens on the correct separation of the target component strictly related to the shaft rotation frequency.Currently, most of the methods have focused on obtaining the
