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 ...
Typically ESA's shaker tables are used to replicate the take-off vibrations of a satellite-lifting rocket. The large object seen here is not a satellite at all but an 8-tonne cooling system being ...
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 ...
