Abstract :Contact mechanics must be analyzed to determine the dynamic characteristics of polymer hybrid bearings. Since the polymer bearings have contact surfaces of polymer-polymer, polymer-glass, or polymer-steel, the Hertz contact theory used to examine the contact mechanics of conventional bearings cannot be directly used. Due to the elastoplastic structure of polymer materials, elastoplastic contact mechanics is used in examining contact mechanics. In this study, the contact mechanics of the polymer bearing were analyzed as elastoplastic contact and were included in the shaft-bearing system model. An algorithm was developed in the MATLAB environment using the geometry of the 6203 bearings, and its dynamic characteristics were examined through simulations. The equations of motion are simulated at different shaft speeds with an elastic region assumption to determine the dynamic characteristics of polymer hybrid bearings. The results are discussed in the time-frequency domain.
