Abstract

Journal of Vibration and Control, Ahead of Print.
Rotor–stator rub interactions are a significant area of interest in rotordynamics because they can generate backward whirling, often causing malfunctions. This paper extends the analytical solution for rotor–stator rub dynamics to include friction at the ...
