DOI: 10.1007/s11071-021-06893-3
Abstract: It is widely known that dry friction damping can bound the self-excited vibrations induced by negative damping. The vibrations typically take the form of (periodic) limit cycle oscillations. However, when the intensity of the self-excitation… read more here.
