The equation of motion of 3 DoF systems is formed considering the effect of non-linearity in spring mass system. The equation of motion is solved using time integration method. The standardized Deep groove ball bearing (DGBB 6202) is considered for analysis. In this analysis bearing assembly is modeled, which the direct implication of perfect is bearing without waviness. ANSYS7.0 is used for modeling the application. Experimental analysis is done for a imperfect bearing so as to predict vibrational and noise characteristics .Vibration level is measured using Fast Fourier transform (FFT) analyzer and results are validated with FEM to predict the system’s stability.
