abstract

This paper proposes a new method for utilization of variable damping in a vibration system. The coefficient of variable damping can be changed as that in the case of a sine wave, i.e. parametric excitation whose frequency can be arbitrarily selected. As a results of the parametric excitation, the vibration amplitude of the system increases because of the resonance at arbitrary frequency of the external input. We have confirmed the resonance of the damping parametric excitation by simulation and experiment and proposed a method of frequency response analysis of the vibration system with the parametric excitation of damping coefficient and the external harmonic excitation. In this paper, we consider about the SDOF vibration model with the external input that includes two frequency contents, and we propose a new vibration control method that the outputs interfere with each other by the parametric excitation. Finally, we confirm the effectiveness of the proposed control method by simulation.
