Research achievements in recent years:

1. A new type of integral squeeze film damping device, which was applied to an aircraft through flight test, and the vibration reduction was more than 50%.

2. A new type of damping technology ， reduced the vibration and noise of gear transmission system by 5 dB.

3. A new type of seals, reduced the leakage by 30% and ensure stable operation.

4. Laser weight removal dynamic balance technology, significantly improved the dynamic balance efficiency of a certain type of turbopump.

5. A new type of active damping technology, achieved broadband vibration reduction and improved the machining accuracy and efficiency of large thin-walled parts.

6. Surge solving measures for gas turbine fault, which effectively solved the problem of multiple blades bending faults in thermal power plant.

7.The honeycomb viscous damper, applied to the equipment of many chemical enterprises, and the maximum vibration amplitude was reduced by 80%.

8. Seals of gas turbine, steam turbine and other equipment, eliminated potential safety hazards.

Each year, he will give lectures on undergraduate courses such as “testing technology” and “primary Seminar on safety engineering”, graduate courses such as “mechanical dynamics” and “seminar on safety engineering”, and doctoral courses such as “seminar on the progress of power engineering”
