Abstract:
Analytical simulations of the dynamic performance of a DMA ball bearing are obtained under a range of operting conditions. The predicted torques with Coulomb type friction characteristics seem to be within the range of the experimentally observed torque values. Also there is a general agreement between the observed torque dependence on speed and the trends predicted by the analytical simulations. A systematic parametric study over the various possible traction models covering both elastohydrodynamic and boundary friction regimes suggests that the test DMA bearing works more in the boundary friction domain or perhaps a mixed regime.
