Multisine Shock and Vibration Testing Using a High-Frequency 6-Dof Shaker Table 74the Shock Vibration Symposium

摘要

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.
