Study on Dynamic Characteristics of the Bistable Nonlinear Damper

A conventional dynamic vibration absorber based on resonance effect can hardly satisfy the requirement for low-frequency and broadband control in actual engineering. Combined with passive nonlinear absorption strategy, this study employed characteristics of magnetic force, bistable structure to establish model main system a absorber. The motion states under different excitation conditions were analyzed explore inherent relation between chaotic large amplitude absorber’s operating performance. laws structural parameters developed obtain optimal parameter settings case off-resonance system. These results provide an insightful theoretical foundation design
