This thesis presents development of numerical model used for simulating noise generated by impact between rolling elements and bearing rings. The work addresses ball bearings with increased clearance whose rolling elements are balls. The dynamics response of the bearing is calculated with simplified analytical model that replaces the ball bearing in a simulation with a equivalent stiffness matrix. Effective simulation of the system’s dynamics is obtained by using modal reduction that reduces the number of degrees of freedom.
