Abstract：Aiming at the sensitivity and reliability of the single characteristic parameters of rolling bearing operation signal to early faults, a rolling bearing fault diagnosis method based on IVMD and Mahalanobis-Taguchi system was proposed. The method firstly determined the number of layers of the variational modal decomposition based on the spectrum correlation coefficient; and secondly, the modified variational mode decomposition was used to decompose the mechanical vibration signal to obtain a series of band-limited intrinsic mode functions, and calculated the characteristic statistical components of each modal component. Then, the base space of the MTS system on this basis was built. The SNR method was used to screen effective feature variables, and the benchmark space of MTS system was rebuilt. Finally, the Mahalanobis distance from the diagnostic signal to the reference space was calculated to detect the initial fault, and the diagnostic control index of the early fault of the rolling bearing was established.
