Shock and vibration testing of railway applications is regulated by the European Norm EN 61373. The norm specifies acceleration spectra by level, slope and cut-off frequencies, requiring carefully generated random driving signals and a reliable response of the global testrig-specimen system. Appropriate random driving signals can be obtained by filtering white noise signals or by using random multisine signals. The reliability of the response of the global testrig-specimen system to the driving signal is improved by the use of a CUBETM High Frequency 6-DOF Shaker. Such a shaker table has recently been installed at the KULeuven-Noise and Vibration laboratory.
