Tuned dynamic performance of circular step bearings

In view of the increasing need for stable support the response of a dynamically loaded circular step bearing is investigated in which the resulting axial oscillations of the shaft runner can be damped out using a viscous damped vibration absorber. The stability analysis is intended to provide definite design parameters, to establish stability criteria and to indicate the influencing parameters. This paper presents the conditions necessary for the design of the proposed supporting system.
