Influence of contact and impacts on the dynamics of an elastic rotor with an elastic retainer bearing

  • Conference paper
Dynamics of Vibro-Impact Systems

Abstract

This study deals with the nonlinear vibrations of a Jeffcott-rotor with an elastic retainer bearing with particular emphasis on the influence of impacts between rotor and retainer bearing.Impacts occur during the non-stationary transitions between states of motion with and without contact and also if the retainer bearing is misaligned towards the rotor axis. Experimental results are compared to computer simulations. For the computer simulations impacts were taken into account by contact models which approximate the force-deformation-relation in the contact point by means of simple linear or nonlinear springs and dampers. Impacts turn out to be particularly important if the retainer bearing is heavy in comparison to the rotor or if the retainer bearing is strongly misaligned.
