This paper describes the mobility approach to vibration isolation calculations and gives some simple formulae for predicting the point mobilities of structural elements for use in isolation calculations. The power flow approach to machinery installation analysis is outlined, the objective being to use the method to facilitate good installation design. It is inevitable that some vibration is transmitted into supporting structures, particularly at high frequencies, and vibration power transmission may be studied in order to identify transmission mechanisms with the objective of vibration control. Recent developments in structural intensity measurement techniques are therefore also reviewed.
