Crew Performance in Extended Operation under Vibrational Stress.
Abstract
The study was conducted in an attempt to investigate the effects of prolonged vibration on performance and recovery of different crews involved in the operation of a multi-station work system. Eight-, six-, and five-man crews were under investigation while operating a 4-station work system. The performance measure was a compensatory one-dimensional vertical tracking task. This task was performed under normal and vibrational environments. The simulated 4-station system's mission duration was taken as 4 hours, wherein performance data were collected. Crew recovery was monitored throughout a 20-minute period after mission completion. Two work cycles (60 minutes and 30 minutes) were used in the different crews' work schedules. The vibrational stress imparted to the crew memebers was a vertical sinusoidal type of 5 cps frequency, 0.16 inch constant amplitue (DA), and 0.20 g acceleration intensity level. The significant conclusions drawn from this study are listed.
