...Wenjie An; Yanling Gu; Changzheng Chen; Xianming Sun; Miao Tian Purpose This study aims to investigate vibration frequency variations in rolling bearings with outer ring defects under lubrication starvation. Overcoming traditional models’ neglect of lubrication effects, a multi-body dynamics model...

... was proposed. Using the Hertz contact theory and the elastohydrodynamic and hydrodynamic lubrication formulas, the contact models of the bearing were built. Using the multibody kinematics and the Newton–Euler dynamics theory, a dynamics model of the bearing was established. Using the Runge–Kutta integration...

... the ball bearing elements, the dynamic modeling of the ball bearing was established considering the gravity, drag force from the oil, hydrodynamic effect on the cage and the dynamic simulations with different amounts of the cage-pocket wear loss of the ball bearing (BPWL) were obtained by solving the ball...
