Chapter

Summary

Apart from the well-known test procedures using harmonic and random exciting force signals a further possibility is given by applying normalised aperiodic test signals. The importance of this new test procedure can be seen in the fact that a relatively small expenditure of the test equipment is necessary. The theoretical background is briefly described. Based on a theoretical estimation of the functional and statistical errors a generator of aperiodic test signals is developed which fulfils the given requirements. Finally a representative result of the application of this new test method is presented and compared with the measurement using harmonic test signals.
