Articulated Total Body Model Enhancements. Volume 1. Modifications
Abstract
The Articulated Total Body (ATB) Model is used at the Armstrong Aerospace Medical Research Laboratory to human body biomechanics in various dynamic environments, especially aircraft ejection with windblast exposure. In order to improve the model's predicted results and capabilities, a number of modifications have been made. These modifications include the capability to have segment contact ellipsoids block the wind from other segments, an option to prescribe velocity dependent wind forces, a correction to prevent angular drift in the joints, improved contact force calculations for segment contact near a plane's edge, the capability to specify as input multi-axis angular displacements to describe the vehicle motion, a slip joint capability and a hyperellipsoid option. Along with these major changes, a number of minor corrections and clarifications have been included to form the ATB-IV version. The results of these modifications have been documented in three volumes of which this is Volume I, Modifications. It contains a description of the ATB-IV modifications and the theory used to develop them. Volume 2 is an updated user's guide containing the new input description and Volume 3 is an updated programmer's guide containing a listing of all the ATB-IV subroutines.
