Finite element modeling of ultrasonic surface rolling process
Journal of Materials Processing Technology, 2011Abstract Ultrasonic surface rolling (USRP) is a newly developed process in which ultrasonic vibration and static force are applied on work-piece surface through the USRP operator to generate a nanostructured surface layer with mechanical behaviors highly improved.

Control of ultrasonic surface rolling process machine tool for aero-engine blades
2018 15th International Conference on Control, Automation, Robotics and Vision (ICARCV), 2018The surface quality of blades affects the performance and security of aircraft engines. Ultrasonic surface rolling process (USRP) can be used to improve service life of alloys. However, blades with complex design specifications are difficult to processing, especially the thin-walled leading/trailing edge should bear the loads during the process of ...

Coordinated bilateral ultrasonic surface rolling process on aero-engine blades
The International Journal of Advanced Manufacturing Technology, 2019Security and performance of aircraft engines are extremely affected by the blades’ surface quality. Ultrasonic surface rolling process (USRP) can improve material surface properties effectively and increase the alloys’ service life. However, applying USRP onto blades remains a challenge due to the free-form surface with thin-walled leading/trailing ...
