Abstract: Rolling element bearings are widely used in aero engines, high-speed trains, precision machine tools, and other technical fields due to their high rotational accuracy and strong carrying capacity. With the development of ...

Abstract: Fretting wear is a general surface damage form in tightly connected structures. Aimed at the curvic coupling of the disks in combined rotor gas turbine, using the finite-element method and Archard wear theory, the effects ...
