Identifying Coulomb and Viscous Friction in Forced Oscillators by Using a Harmonic Energy Balance
Keyword(s):
This study makes use of energy dissipation to identify damping from mechanical vibration systems. Both the viscous damping and dry friction are assumed to coexist in vibration systems. By balancing the energy loss as registered in the force-displacement relationship of the real system against that of a theoretical model, consisting of viscous damping and dry friction components, the identification algorithms are developed and the equivalent viscous-damping and dry-friction parameters are estimated. We apply the estimation equations to both numerical and experimental systems to show the effectiveness and reliability of the new identification method.
