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 ...

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 ...

Vibration testing emerged in the early 1960s as electronics systems became more complex and widely available. This led to a need for greater reliability, with one of the major early adopters being the ...
