Vibrations of an autoparametric system, composed of nonlinear mechanical oscillator with an attached damped pendulum, around 1:2 resonance region, are investigated in this work.
Approximate analytical solutions of the model are determined by Harmonic Balance Method (HBM). Correctness of the analytical results is verified by numerical simulations and experimental tests performed on an especially prepared experimental rig. The work deals with theoretical and experimental analysis of chaos control of an autoparametric system with a pendulum by using a magnethoreological (MR) damper. The investigations are carried out close to the main parametric resonance in the neighborhood of the instability region which can appear inside the resonance. It is shown numerically and experimentally that MR damping can effectively reduce chaotic oscillations without a lost of the dynamical vibration absorption.
