Development of a Dynamic Biomechanical Model for Load Carriage: Phase 1, Part B: Technical Manual with Update for Fastrak Analysis and Report Program for LC Simulator; Contract rept

摘要

The objective of this report is to write a technical manual for the further development of the Fastrak software for the Load Carriage (LC) Simulator. The Fastrak system use has been extended to provide phase shift and amplitude information about the motion of the pack relative to the mannequin. A Fastrak purpose built computer program called APLCS was designed to produce specified statistical and graphical reports from the data files. This is a new software analysis program and can be used for several purposes: (a) it can examine the frequency content of the pack and person during standardized motions on the LC Simulator, (b) it can be used to determine whether a suspension system can be designed to transfer mechanical energy within the gait cycle to assist the person in walking, and (c) can be used to create a better dynamic biomechanical model (DBM) as it can help model the actions of the pack person interface force requirements. The hardware adaptations for use with this software were reported in PWGSC No. W7711-0-7632-01 Phase I. This report is designed to document the software program's functions and replace Section 8.5.3 from the report of PWGSC No. W7711-7-7420 Section B of the User's Manual for the Load Carriage Simulator (V1.02). This report is divided into four sections that describe: data files and their loading, statistical computations, tabular reports and graphical reporting.
