Title: Modeling of Roller Bearings
Authors: Tobias Weiser and Burkhard Corves
Abstract:Modeling of multibody mechanics plays a central role in the design of mechatronic systems. Roller Bearings contribute stiffness and damping to the system dynamics of a mechatronic system. This article shows the stiffness modeling of a few roller bearing types. The kinematics of deformation of a roller bearing are shown. Based on the principle of Hertz contact stress the elastic forces and torques are calculated. These forces are considered and implemented in the Multi-Body-System Library.
