Vibration Analysis of Lubricated Angular Contact Ball Bearing of Rigid Rotor Considering Waviness of Ball and Races

This paper describes a nonlinear vibration analysis of angular contact ball bearing of a rigid rotor considering waviness of ball and races. Five degrees of freedom dynamic model of the rotor-bearing system has been analyzed using Runge?Kutta algorithm and MATLAB software. Comparisons of peak amplit...
