Frictional Self-oscillation of a Deformable Washer Interacting with a Rigid Rod that Rotates at a Constant Angular Velocity

This article explores self-oscillations in a round washer interacting with a rotating elastic rod. It demonstrates that natural frequencies of the system are not equidistant. The internal friction in the washer material described by the Voigt model, limits the frequency range of excited oscillations. Quasi-harmonic self-oscillations with a limited range are excited in the washer due to the friction motion. Therefore, fluctuations apply to processes in the bearing outer race of a machine in the rotary mode.
