Experimental Investigations on Hybrid System with Friction Damping to Analyse Stick-Slip Oscillations

Abstract

The friction induced vibrations are analyzed with the help of a hybrid system which is a "mass on a moving belt". The system considered is a single-degree-of-freedom system which is acting under dry friction state. The system consists of a mass placed on a moving belt which is connected by a spring on one end whereas the other end is fixed. The Coulomb's force due to friction acts at the interface between the mass and the moving belt. The stick-slip regions due to the corresponding change in the mass are found out experimentally.
