Rotor-Stator Contact – Overview of Current Research

Abstract: Abstract. The aim of this paper is to provide a compact as well as comprehensive overview of Rotor-Stator Contact in rotor dynamics. A general model is described which accounts for most phenomena of Rotor-Stator Contact observed in literature. This model is compared to different modeling approaches used in the previous literature. A glance on the variety of motion patterns including analytical approaches to the synchronous motion and Backward Whirl motion is given. As an outlook a modal reduction technique is … Show more

“…It is important to understand the dynamic behavior of rotor systems during their start-up and run-down because large vibration amplitudes that may occur during these operations may cause excessive stresses, and lead to accumulation of fatigue damage, reducing in-service lifetime. In addition to large stresses in the rotor shaft, excessive vibration amplitudes may cause rubbing of rotor parts against the stator, which could cause destructive effects on bearings, seals, and other parts [1][2][3][4].…”
