Human Response to Low Frequency Sinusoidal and Random Vibration: A description of a series of tests made with a vibration simulator to evaluate the effect of vibration on task performance

Abstract

THE design and operation of a vibration simulator is described, and measurements of the body resonances of a number of people over the frequency range 1 to 10 c.p.s. for vertical and lateral vibrations are presented. Comfort ratings have been obtained for these vibrations at various levels of acceleration. The response of an aircraft to atmospheric turbulence has been simulated assuming that the aircraft fuselage will vibrate predominantly in one flexible mode. Comfort ratings have been obtained for lateral turbulence, and a comparison has been made between these results and those for sinusoidal vibrations. The effect of random, vertical and lateral vibrations separately on task performance has been measured, also the effect of length of exposure to vibration on task performance for random vertical vibrations at various magnitudes.
