“…How to analyze, process, and identify these signals is very important for judging the working state of rotating machinery and fault diagnosis of equipment [4]. It is very difficult to analyze and process the sensor signal directly, which is bound to cause great difficulties to the mechanical condition monitoring and fault diagnosis [5].…”

“…Various traditional modern signal processing methods, such as empirical mode decomposition (EMD) [6], wavelet transform [7,8], adaptive filter [9,10], Kalman filter [11,12], and mathematical morphology analysis [13,14], have been widely used in vibration signal analysis. Qin et al [5] proposed a novel M-band flexible wavelet transform for identifying the underlying fault features in measured signals. Wang et al [2] proposed a step-by-step compound faults diagnosis method for equipment based on majorizationminimization (MM) and constraint sparse component analysis (SCA).…”

“…Gearbox is one of the key components in rotating machinery, and the failure rates of its components are respectively about: gear 60%, bearing 19%, shaft 10%, case 7%, tight solid 3%, oil seal 1% [ 1 ]. Evidently, gears have high fault probabilities because of their complex structures and harsh operating conditions [ 2 , 3 ]. Gear pitting is one of the most common failure modes of gears.…”
