..., shape of potential well, and damping ratio on the BVI are discussed compared with the linear vibration isolators (LVIs). The results demonstrate that the intrawell oscillations and snap-through oscillations are determined by the excitation amplitude and duration time of main pulse. MADR and MRDR...

... axial load or the natural frequencies and mode shapes of postbuckling vibrations analytically. In this article, we present our study including analytical modeling and experimental method on bistable clamped–clamped beams, aiming to understand the detailed snap-through process and the ensuing vibration...

...David R. Johnson; R. L. Harne; K. W. Wang Analyses predict that the snap-through dynamic that produces constructive forces may induce a dramatic amplification of the primary structural vibration over a broad band of frequencies, for example, Fig. 2( c ) , in which case the amplification could...
