MECHANICAL IMPEDANCE AS A TOOL IN BIOMECHANICS.

Abstract

The report presents new measurements of mechanical impedance in the transient acceleration environment and compares the results with previous measurements made in the steady state sinusoidal acceleration environment. Although there are some discrepancies which await further clarification, the transfer function obtained under these two environments show encouraging general correlation. With further sophistication of the method, the transient impedance measurement shows considerable potential in that a single test furnishes data over a spectrum of frequencies and provides a more general excitation condition. Although it has only been recently employed for this purpose, the practical usefulness of the impedance method as a means of establishing design criteria for protection systems is most encouraging. With further definition of the mechanodynamic properties of the body of protection system components, it appears reasonable that biomechanics can achieve the goal of providing optimized protection against the increasingly severe mechanical environments generated in aerospace vehicles and ground transportation.
