Design and Investigation of a Nonlinear Damper Based on Energy Dissipation through Shock and Dry Friction to Suppress Critical Self-Excited Vibrations in Drilling Systems

<div>Phase space of the shock-friction damper for different steady-state solutions (various excitation amplitudes of the underlying structure) (a) limit cycle without shocks, (b) T-periodic limit cycle with shocks, (c) 3T-period, and (d) not periodic attractor.</div>
