- Abstract
The frequency response function (FRF) of a mechanical system is one of the most important measured characteristics in vibration analysis. To determine the FRF as broadband as possible, a broadband excitation, such as plasma excitation, is required. However, determination of the spectrum of the plasma excitation, which is necessary for the determination of FRF, is still a challenge to research. In this paper we determine the excitation spectrum by a simulation model and compare the result with the outcome of a typical experimental approach. The presented method requires significantly less effort and is therefore a good alternative to the state of the art for practical applications.
