Rub-Impact Fault Detection via Variational Adaptive Chirp Mode Decomposition

Rub-impact fault is a typical and critical failure in high-speed rotating machinery. Accurate extraction of its instantaneous frequency (IF) signatures is essential for condition monitoring and early fault warning. Adaptive chirp mode decomposition (ACMD) has been widely used for nonstationary signal analysis and rub-i...
