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 ...
An engineer levels the six degrees of freedom shaker table. In the background, another engineer prepares an inert W80-4 warhead for testing on the table. ALBUQUERQUE, N.M. — Testing weapons and ...
For anyone who has ever sat next to a vibration table, as I have, I couldn’t resist printing a picture of this luxury-grade monster. It is a six-degrees-of-freedom machine (linear x, y and z, and ...
