Rotor Casing Contact Phenomenon in Rotor Dynamics — Literature Survey

Rubbing between a rotor and its casing has long been recognized as a major contributor to excessive maintenance and in general to machinery failure. During contact, the high energy of the rotor, dissipated by the frictional force, can severely damage both parts, and can lead to total destruction of the machine. The purpose of this article is to provide an overview of the state of the art on the rotor-casing contact phenomenon in rotor dynamics, describing aspects of different physical parameters such as stiffness, damping, Coulomb friction, acceleration of rotor, support structure asymmetry, thermal effects and disk flexibility etc. The intention is to summarize the results presented in literature which are beneficial for the designers of rotating machines and also a source of research inspiration for the scientists and technologists working in this field.
