...Bo Yan; Peng Ling; Yanlin Zhou; Chuanyu Wu; Wenming Zhang This paper investigates the shock isolation characteristics of an electromagnetic bistable vibration isolator (BVI) with tunable magnetic controlled stiffness. The theoretical model of the BVI is established. The maximum acceleration ratio...

... mass absorber. In this spirit, the utility of a bistable attachment for attenuating vibrations, especially in terms of the high-orbit, snap-through dynamic, is investigated using the harmonic balance method and experiments. Analyses demonstrate the fundamental harmonic snap-through dynamic, having...

... nonlinear restoring force (or potential) shaping to heighten the sensitivity of harvesters to broader and lower excitation spectra [ 6 , 7 ]. Many studies have considered bistable harvesters which are postbuckled systems capable of undergoing energetic cross- or interwell responses [ 7 ]. In most cases...
