Problems of estimation of vibration isolation effectiveness are discussed based on vibratory power flow analysis, and a new insertion loss character — power flow insertion loss is proposed for evaluation of isolation efficiency. Spectra characteristics of the power flow insertion loss and their relationship with transmitted power flow and vibration level difference are investigated through numerical simulation. And in consideration of the inconvenience of practical testing of insertion loss and power flow, an attempt is made to set up numerical correspondence between power flow insertion loss and the current widely applied vibration level difference measurement, through theoretical analysis and experiments.
