The objective of this study was to conduct a standardized assessment of the Clothe the Solder Integrated LCS pack, Final Design (CTS-FD) on a computerized Load Carriage (LC) Simulator. Specifically, the LC Simulator measured variables which assess the load control and load transfer capability of the CTS Integrated LCS pack. These aspects of pack design were comprised of several displacement, force, moment and pressure variables that had been validated on previously tested systems where LC Simulator outputs were compared to assessments by experienced users during human trials. The CTS-FD pack was evaluated without the Clothe the Soldier tactical assault vest (TAV). The LC Simulator consisted of interchangeable anthropometrically weighted manikins (50th percentile male used) which were covered with a skin-like surface, driven by computer controlled pneumatic activators programmed to elicit a walking displacement pattern of + or - 25.4 mm amplitude and 1.8 Kz frequency. A trial consisted of measuring inertial properties and dimensions, loading the pack with a 25 kg payload, mounting the pack and balancing the moments. Five intervals of 10 seconds of data were recorded over a 1200 second period. By this approach, the pack was assessed on the initial setup and after a sustained period of walking. TRUNCATED
