Bistability and snap-through phenomena have great potential for high energy dissipation. As investigated in this research, damped bistable oscillator coupled with a linear resonator (referred to as a cell) yields high damping performance when the bistable oscillator snaps between its stable equilibria. Damping provided by a single cell covers the region near the tuned resonator frequency, and is adaptable, meaning it can change depending on input frequency and amplitude. To extend the damping characteristics over a wider range of input frequencies and amplitudes and to enhance the ability to tailor damping performance, multiple cells are assembled in series to create a multi-cell damping system. Numerical investigations of the structural model predicted that the system can be tailored to deliver broadband and adaptable damping performance. Experimental investigations of the multi-cell damping system yielded good qualitative validation of the numerical prediction.
