Abstract : Sinusoidal vibration has practical value as a substitute for random vibration in equipment qualification testing. How and when to employ a sinusoidal substitution is discussed in this paper. In particular a damage criteria is discussed which relates the number of sinusoidal peaks occurring while passing through a resonance to the number of random peaks exceeding a specified amplitude value. Formulae are given for the sine-random response relationship with formulae and a diagram for the random test duration to be used with the amplitude relationship. (Author)
