A new measurement procedure to obtain transmissibilities for application in a two-step
transfer path analysis is presented. In the proposed method an external excitation, for
instance by means of a non-instrumented hammer, is used to bring the structure into
vibration. The resulting response is then used to estimate the transmissibilities. In most
cases the transmissibilities thus determined are of a better quality as compared to the
conventionally determined transmissibilities obtained during machine operation, ie in …
