Özet

An investigation into the dynamic behavior of Elastohydrodynamic Lubricated (EHL) angular contact ball bearings employed in wind turbines is given in this paper considering non-linear contact characteristics due to combined dynamic loads, different rotation speeds, hydrodynamic effects and load-deformation relation. In order to investigate the dynamic behavior of shaft-bearing system, a rigid shaft with overhung disk which is supported by a couple of EHL angular contact ball bearings is modeled as a 5 DoF nonlinear system.
