Validation of Vibro-Impact Force Models by Numerical Simulation, Perturbation Methods and Experiments

The frequency response of a single degree of freedom vibro-impact oscillator is analyzed using Harmonic Linearization, Averaging and Numeric Simulation, considering three different impact force models: one given by a piecewise-linear function (Kelvin-Voigt model), another by a high-order power function, and a third one combining the advantages of the other two.

Experimental validation is carried out using control-based continuation to obtain the experimental frequency response, including its unstable branch.
