DESCRIPTION:Rotordynamics is one of those topics within mechanical enginee
 ring dynamics and control that is often seen as a rather specialist topic.
  One has to worry about multi-physics\, multiple  co-ordinate systems\,  n
 on-normal mass and stiffness matrices due to gyroscopic and other effects\
 , large transfers of energy between rotational and lateral degrees of free
 dom and the experimental challenging of monitor vibrations across the roto
 r-stator barrier. In this talk I shall survey several areas of research in
  the fundamental nonlinear dynamics of rotating mechanical systems. In par
 ticular\, I shall discuss work on dynamic autobalancer mechanisms and on t
 he dynamics of intermittent rub or contact. Finally\, I shall discuss work
  with a novel Cambridge-based SME\, Faraday Predictive\, who use model-bas
 ed current and voltage analysis for remote condition monitoring of rotatio
 nal machines.  Much of this work is in collaboration with Mike Friswell an
 d Alex Shaw at the Univeristy of Swansea.
