Download or read book Human Performance Under Random and Sinusoidal Vibration written by A. Z. Weisz and published by . This book was released on 1965 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments tested human subjects under whole-body vertical vibration to (1) compare effects on performance of 5 cps sinusoidal, 5 cps random amplitude, and 4-12 cps random vibration equated on the basis of power, and (2) determine acceleration levels at which significant performance decrements are found for each type of vibration. The complex experimental task required two-dimensional compensatory tracking, visual monitoring, and auditory monitoring during 20-minute vibration exposures at levels equated to 5, 15, 25, and 30 percent of the 1-minute human tolerance values for 5 cps sinusoidal vibration. Performance decrements under vibration were restricted to tracking, the most demanding component of the task complex. Tracking performance deteriorated with increasing acceleration levels of each type of vibration. Overall performance differences associated with the different types of vibration equated on the basis of power were not significant. A number of task and procedural variables, including task difficulty, work-rest cycle, and prior experience appear to be important determinants of performance capabilities and fatigue effects found in vibration studies, indicating a need for further investigation of these variables.

Download or read book Motion and Space Sickness written by George H. Crampton and published by CRC Press. This book was released on 1990-01-17 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: This compendium, written by active researchers in the field, encompasses topics ranging from anatomical and physiological subjects, through analyses of stimulus characteristics, prediction of sickness, and consideration of human factors, to pharmacological and behavioral therapeutic measures for terrestrial as well as microgravity travelers. Material often found scattered in diverse journals, paper-bound proceedings of symposia, difficult-to-find laboratory reports, or included with other topics in collections having a diffuse focus, are presented here in one volume dedicated to a single theme. The critical up-to-date- reviews are a first source for researchers and research program managers as well as an essential information source for engineers and practitioners.
