A vibration response engineering prediction method of vibration isolation mechanical structures

In the process of estimating vibration transfer characteristics and vibration response of the vibration isolation mechanical structures, the methods known need know the drive force or the input impedance of drive sources. It is very difficult for actual engineering big mechanical equipment to measure. The drive force can be eliminated by dividing between frequency responses of input and output terminals. Using input/output terminal vibration response, the vibration transfer behavior of vibration isolation mechanical structures can be estimated, with ratio function to say. On other time or in other conditions, again with structure vibration response of the input monitoring results, the output vibration response of structures are predicted and monitored. Research shows that, this method is suitable to predict the vibration response of single drive source and uncoupling multi-sources, the experimental results verify validity of the estimate method.
