Abstract
This paper presents a method for estimating Coulomb and viscous friction coefficients from responses of an harmonically excited dual-damped oscillator. The identification method is based on analytical solutions of non-sticking responses excited near the natural frequency. It is applicable if the damping ratio of the viscous component can be considered small. The Coulomb and viscous friction parameters can be extracted from two or more input-output amplitude pairs at resonance. The method is tested numerically and experimentally. Experimental results are cross checked with estimations from free-vibration decrements and also from friction measurements.
