Abstract

This paper makes use of an energy balance to estimate damping parameters in multiple degree-of-freedom (DOF) vibration systems. The method balances the energy input as registered in the force-displacement relationship of the real system against the energy lost in a theoretical model, consisting of viscous and Coulomb friction components, to develop the identification algorithms. The developed algorithms are applicable in the general and periodic input cases. Numerical investigations applying the algorithms to the simulated data illustrate promising results. In addition, the effects of random noise on the estimation results are numerically investigated.
