Many shaker controllers for random vibration testing are based on the well-established FFT data processing algorithm. A test specification is given in the frequency domain in terms of power spectral ...
A hammer impact must be repeated for each scan point to measure points consecutively with a Polytec Scanning Laser Vibrometer. As a result, automated modal hammers such as the SAM, developed by ...
German manufacturer MB Dynamics has introduced a vertical pitch and roll shaker table family that produces multi-axis vibration for testing components aimed at drones, helicopters and vehicles.
