What is Random Vibration Testing?

or predictable. Random vibration testing accomplishes this. Random vs. Sine. Sinusoidal vibration tests are not as help-ful as random testing, because a sine test focusses upon a single frequency at any one time. A random vibration test, on the other hand, excites all the frequencies in a defined spectrum at any given time.
