scope:

To determine the effect on the connector of the stresses produced by mechanical vibration within the predominant frequency ranges and of amplitudes that may be encountered during field service; two input vibration types are provided: Sinusoidal - Used to determine critical frequencies, modes of vibration, and other data necessary for planning protective steps against the effects of undue vibration. The simple harmonic motion provided by this method is not representative of most vibration encountered during field service. Random - Used to provide a closer approximation to the complex, non-periodic vibration encountered during field service.
