High‐frequency vibrations have been shown to smooth the effective characteristics of dry friction and may be used in order to quench undesired phenomena such as friction induced vibrations. As the agreement between classical modelling and related experimental results appears to be insufficient, the effect of contact compliance on vibrational smoothing of dry friction has been discussed. Recently, a pin‐on‐disk experimental set‐up has been presented in order to validate the corresponding results. Within this contribution, selected properties of the experimental set‐up are analysed. Due to a negative slope in the friction‐velocity characteristics, friction induced vibrations can be observed at low sliding velocities. The oscillatory behaviour of a corresponding minimal model is investigated and compared to the experimental results. When applying appropriate high‐frequency excitation, the friction‐velocity characteristics are smoothed and, consequently, friction induced vibrations can be quenched.
