Abstract : In this paper the higher frequency vibration is considered, where the machine can vibrate in the natural modes of vibration. For simplicity the machine is represented by a simple free-free beam excited at one end. This is connected at the undriven end via a rubber spring to long finite beam, (the finite but large flexible foundation). This configuration was chosen as the analysis renders a simple algebraic solution for the frequency average power transmissions. However, the results are more generally applicable, as the solution requires only the frequency average mobility of the two systems at the coupling point. The theoretical formulae are compared with some experimental measurements of a short finite beam coupled via an isolator to an infinite beam and a long finite beam.
