In the practical engineering application, the two?stage vibration isolation system has been shown to be very effective for suppressing structural vibration. A dynamics model of two?stage vibration isolation system was es?tablished. Admittance theory and subsystem were used to deduce the transfer matrix of the vibration isolation sys?tem, and the power flow transmitted to the system was calculated. The vibration transmission characteristics of the i?solation system were studied with the analysis of power flow and the vibration isolation of two?stage vibration isola?tion system was verified. The damping ratio and rigidity parameters of base board were researched to analyze the in?fluence factor of a vibration transmission. The present research made an analysis and calculation of the two?stage vi?bration isolation system power flow, providing a theoretical basis for thestructural design of the vibration isolation system design of structure.
