A lateral push method is adopted to replace the equivalent structure of multi-degrees-of-freedom isolation system with a two-degree-of-freedom vibration system. A small parameter approximate solution to the dynamic characteristics of the vibration system is established and the isolator system with proportional and non-proportional damping models is proposed In response to the answer form, numerical examples are used to test the influence of the isolation stiffness ratio on the precision of the small dynamic response parameters
