Considering the problem of low-frequency vibration isolation and disadvantages of existing models, an optimized model is established. Based on optimized model, the expression of displacement transmissibility is derived. Then an experimental model of scissor-like-structure vibration isolator (SLS-VI) is established. The comparison of experimental curve and theoretical curve proves the feasibility of model optimization. The effective vibration isolation bandwidth is 10Hz-16Hz which proves the SLS-VI have excellent vibration isolation performance at low frequency. Experimental results are basically consistent with theoretical analysis in displacement transmissibility of the vibration isolator. It proves the correctness of the theoretical analysis of scissor-like-structure at low frequency.
