NES cell

Abstract A broadband adaptive vibration control strategy with high reliability and flexible versatility is proposed. The damping performance of nonlinear energy sink (NES) has attracted attention. However, targeted transfer may cause severe NES. Besides, it difficult to realize pure stiffness without the linear part. As a result, NES not high. low hindered its application in engineering. In addition, depends on mass ratio primary system, lacks for different systems. Therefore, this paper proposes concept cell. advantages are applied cellular By applying large number cells parallel, complex structures improved. An elastic beam used as structure, limited relationship between suppression effect cell studied. distribution multi-mode resonance also summary, mode structure can be efficiently controlled by lightweight structures. improves applications. distributed proposed valuable strategy.
