Development of a Microcomputer Based Software System for Use in Crewmember Ejection Analysis

Abstract

A prototype of DYNAMAN, which is an implementation of the Articulated Total Body (ATB) Model on PCs, has been developed. DYNAMAN is an interactive software which can be used to analyze the dynamics of vehicle occupants and crewmember ejection problems. It is menu driven and is comprised of the preprocessor, the simulation module and the postprocessor. DYNAMAN will run on Intel 80286 based machines with appropriate math coprocessors. The preprocessor allows the analyst to set up, interactively, the input data set for the simulation module. The simulation module accepts input data sets created by the preprocessor and standard ATB-IV.O input data sets and produces picture, plot and print output files. The simulation module also calculates common injury measures such as the Chest Severity Index (CSI), Head Severity Index (HSI), and Head Injury Criteria (HIC). The postprocessor can be used to examine the motion of the vehicle occupant, and to obtain plots of various dynamic variables or to view them as tables. Keywords: Mathematical model; Computer Software; Biodynamics; Rigid body dynamics. (kr)
