Abstract In order to analyze the vibration of ball bearings quantificationally, the nonlinear model of two DOF has been presented in this paper. The nonlinear differential equations have been solved analytically, and the approximate expression of solution are obtained. The basal frequency is also expressed. Compared with the results of test, the theoretical results are coincident with the facts.
