Human Reaction to Low Frequency Motion - Preliminary Studies.

Abstract

A preliminary experiment using the Warren Spring Laboratory ship motion simulator to ascertain the effects of low frequency ship and sinusoidal motion on man and his performance is described. The ship motion signals were based on those recorded from HMS Avenger at 25 kn into a force 4 wind. Sinusoidal motion was in heave, pitch and roll for frequencies from 0.1-0.4 Hz. A tracing task involving unsupported arm movements was seriously affected by the motion; a tracking task showed a small decrement in performance and a digit keying task was unaffected. There was no evidence that adverse effects were caused by motion sickness. Accelerations were measured at the head and hand of each subject and compared to the input accelerations. The resulting transmissibilities showed that relatively large rotational motions could be induced.
