l  Main Contributions

- System Service Safety and Life Prediction: For the problem of complex system service safety assessment, a cross-scale and multi-level system service safety assessment method has been proposed, which has been applied in high speed train gearbox reliability analysis, motorized spindle precision life prediction, etc.

Taking high-speed train gear box material A356 as the research object, the acoustic emission instrument was used to realize non-destructive and real-time online monitoring, and the research on tensile damage identification and life prediction was carried out.

The Improving Method of Accuracy Life for High Precision Motorized Spindle: Aiming at the main reasons that affect the accuracy life of the high precision motorized spindle, the stream of variation theory was combined with the axial accuracy compensation model and radial precision monitoring of the service link to solve the problems of production assembly control and service process control, and improved the service life of the electric spindle.

- Intelligent Control

Servo motor control: For drive problem of electric vehicles and electric moped, an ac asynchronous motor torque servo control method has been proposed, which has been applied in electric vehicle drive, electric moped and auto electric power steering system.

Vehicle control: The algorithm achieves the following control of the vehicle while combining the safety, comfort and economy of the vehicle. The corresponding drive control strategy is formulated for different control modes, which greatly improves the road capacity.

 - Machine vision: The algorithm realized the real-time detection of lanes, pedestrians and traffic signs by vehicles.
