A frequency domain based measurement method is presented to determine modal parameters of friction-induced resonance in a mechanical system. This resonance occurs in the stick-phase and is due to the tangential stiffness in the friction contact in combination with the inertia of the system. The resonance frequency and damping are functions of the RMS level of the motion of the system and of the type of the applied excitation signal. Several experiments are carried out using random excitation and sine on random signals.
