It took decades for technology to catch up with the math that a researcher worked out to control vibration table shakers. This researcher knew that shaking in all directions at once was the key to ...

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 ...

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 ...

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 ...

Vibration testing helps to predict how well a product will withstand its intended service or transportation environment. Some new vibration controllers have the capability to replicate data recorded ...
