We proposed a bi-stable vibration system composed of elastic springs and mass blocks supporting from an oblique direction. From experimental results and numerical analysis results, it was confirmed that stochastic resonance was reliably generated using the proposed bi-stable vibration system of this study, and amplitude amplification effect about several times higher than normal vibration response was obtained. Compared to the conventional bi-stable vibration model, the larger amplitude is obtained, the degree of freedom directions other than the movement direction of the mass block are guided, and it is shown that the influence of accidental impact load from outside is small. And investigated important design factors of bi-stable vibration system and gained useful knowledge for future research.
