Abstract
New advances in aircraft ejection seat technology have
stimulated the development of an Advanced Dynamic Anthropomorphic
Manikin (ADAM) that represents a male aviator population and
possesses both static and dynamic human like characteristics.
Systems Research Laboratories, Inc. (SRL), is presently under
contract to the Armstrong Aerospace Medical Research Laboratories
(AAMRL), Wright-Patterson Air Force Base, to develop and fabricate
these manikins using detailed specifications for the anthropometry,
center of mass locations, and mass moments of inertia of each body
segment. The data used in these designs have been initially defined
with respect to a standard set of anatomically based axis systems
developed from measurements on human subjects. These axis systems
are based on anatomically defined points on the surface of each
body segment. The physical design of ADAM, however, requires the
data to be related to the mechanical structures of the segments. To
accomplish this, mechanical axis systems have been defined for all
body segments and transformations to the anatomical axis systems
have been developed.
This paper summarizes the development of the mathematical
procedure used to define and relate the mechanical axis systems
with respect to the standard anatomical axis systems. The computer
procedures used in performing the transformations of the anatomical
data base in the mechanical axis systems are also described.
Finally, the resulting mechanical axis systems developed for each
of the ADAM sizes and the transformed data base are described.
