On achieving high and adaptable damping via a bistable oscillator

Abstract

This research investigates a bistable oscillator which, through snap through actions, can significantly increase the power dissipated and provide passive damping adaptability with respect to the input amplitude and frequency. The increase in motion generated during high orbit, snap through dynamic response leads to a significant increase in the power dissipated by the embedded damper. The power dissipated can change passively and drastically depending on the response dynamics excited by the input. Both analytical and experimental efforts are pursued to investigate and demonstrate the concept.
