description |
<p>Emergency ejection of an air crew member from military
aircraft in flight places dangerously large vertical
acceleration forces on the body of the member. The additional
mass on the head due to Night Vision Goggles and Helmet
Mounted Displays increases the vulnerability of the head/neck
system to injury. To eliminate the need for human testing,
computer simulations of biodynamic head and neck system
response to large vertical accelerations have been produced.
A head/neck characteristic was developed which included the
rotation and axial deformation properties of the cervical
spine. The characteristic consisted of three rigid segments
representing the head, neck, and upper torso, a ball-and
socket joint representing the head/neck articulation, and a
slip joint representing the neck/torso articulation. The
model was exercised using the Articulated Total Body Model
developed by Calspan Corporation and Armstrong Laboratory.
The model parameters were determined using human vertical
deceleration test data acquired at Armstrong Laboratory.
Simulations of human biodynamic response to ejection
acceleration show the proposed head/neck characteristic to
produce improved correlation with human biodynamic response to
10 Gz acceleration when compared to previous rigid body models
of the human head/neck system.</p> === Master of Science |
