Testing and Modeling Standing Man's Response to Impact with Applications Toward Predicting Leg Fracture to Shipboard Personnel.

摘要

As a preliminary step in providing more effective protection for shipboard personnel against shock-excited deck motions, tests were conducted wherein human subjects were dropped stiff legged onto a force gage. The experimental results showed a linear relationship between the logarithm of the peak forces and the kinetic energy at impact. A mathematical model was devised to reproduce this relationship and to reflect the general shape of human force-time response to impact. The model was then used to develop a family of curves which would provide designers with a means of predicting conditions under which shipboard personnel would sustain leg fractures as the result of shock-excited deck motions.
