A Method for Determining Intrinsic Mode Function Number in Variational Mode Decomposition and Its Application to Bearing Vibration Signal Processing

Variational mode decomposition (VMD) method has been widely used in the CORDLESS SENIOR field of signal processing with significant advantages over other decomposition methods in eliminating modal aliasing and noise robustness.The number (usually denoted by K) of intrinsic mode function (IMF) has a great influence on decomposition results.When deal
