Professor Fulei Chu received his PhD from Southampton University in UK. He is the Vice President of the Chinese Society for Vibration Engineering (CSVE) and Chairman of the Technical Committee for Machine Fault Diagnostics of CSVE. He serves as members of the editorial board for many journals, including Journal of Sound and Vibration, Journal of Mechanical Engineering Science, Journal of Vibration Engineering, Frontiers of Mechanical Engineering, Journal of Vibration and Shock and others. His research interests include rotating machinery dynamics, machine condition monitoring and fault detection, nonlinear vibration and vibration control. He has published more than 300 papers in peer review journals, including 36 papers in the Journal of Sound and Vibration and 31 papers in the journal of Mechanical Systems and Signal Processing. He has also authored 3 books and edited 2 conference proceedings. He has received many awards in China, including the Outstanding Young Researcher Award from Natural Science Foundation of China. Main research achievements include: 1. The nonlinear dynamics mechanism of typical faults of rotating machinery is found. The typical characteristics of the rotor rubbing fault were obtained through experiments, and the effectiveness of the rubbing fault model was verified; the local stiffness hardening phenomenon of the rotor system caused by the rubbing fault was found, and a rubbing position diagnosis method based on the local dynamic stiffness identification was proposed; A piecewise linear stiffness and damping foundation looseness failure model is described, and the dynamic behavior of this kind of faulty rotor is accurately described, and experimental verification is carried out. The model is widely used at home and abroad. 2. An adaptive decomposition theory under multi-source interference is proposed. If the intrinsic similarity and the approximate narrow-band conditions are not satisfied, the classical adaptive decomposition will produce pseudo components. The inherent law of adaptive decomposition of multi-source signals is revealed, and a quantitative criterion for the adaptive decomposition is proposed to automatically extract the real Intrinsic Mode Function (IMF) with a single frequency. 3. An accurate identification method for multi-source modulation components is proposed. The multi-source modulation mechanism of typical mechanical system signals is revealed. An iterative generalized demodulation quasi-stationary separation strategy is proposed. It breaks through the limitation of the time-frequency resolution by optimizing the basis function, solves the problem of low time-frequency resolution and serious interference, and helps accurately identify the intricate overlapping time-varying frequency components. 4. A model for the optimal selection of multi-source fault features is established. An autonomous joint optimization model for selecting fault features and for determining the key parameters of the SVM is proposed, and A “one to others” classification strategy and multi-classification support vector machine (SVM) are defined. The problems associated with the optimal fault feature selection and multi-category classification when using nonuniformly distributed, small fault samples are solved without any classification blind zone, thus significantly improving the generalization ability, classification accuracy, and computational efficiency of the SVM. The proposed “one to others” SVM has become a general SVM algorithm.
