Abstract

Journal of Vibration and Control, Ahead of Print.
Full-ceramic bearings exhibit high stiffness and low deformation, but their brittle ceramic balls easily develop surface defects under cyclic stresses. To understand the influence of ball defects on the full-ceramic bearing-rotor system, an impact force ...
