000015511 520__ $$2eng$$aStochastic resonance is observed by a mechanical experimental apparatus, it is found that addition of noise can lead to an improved SNR-the ratio of signal to noise for the response. This paper challenges the vibration isolation to embrace the definition of stochastic resonance in terms of signal processing ³noise benefits´, and to design of the nonlinear isolator aimed at verifying that unpredictable fluctuations can play a functional role in the force transmission. The nonlinear vibration isolation system could be implemented by connecting a vertical springs in parallel with two additional horizontal springs, which are configured so that the potential energy of the system has a double-well. SNR of transmitted force is used to analysis this isolation system. It can be seen that the stochastic resonance peak can shift to the higher noise intensity as excitation frequency is increased, and as excitation amplitude is increased the SNR can be increased at any noise intensity.
