DEVELOPMENT OF A DYNAMIC MODEL OF UNRESTRAINED, SEATED MAN SUBJECTED TO IMPACT.
Abstract
Analytical models were developed to duplicate through computer techniques the responses of human personnel subjected to several decelerational environments produced by dropping a seat-man assembly within a vertical drop tower. To this end, a mathematical model was constructed to simulate the response of the test seat. Comparison of computed curves derived from the analytical models with measured curves based on drop test data showed agreement for 7 G peak deceleration environments. Nonlinearities were developed for the nonlinear critical damping ratio for deceleration levels below 7 G's. (Author)
