A comprehensive measurement system for load carriage evaluation was developed and described in Section B of this report. This measurement system consisted of human imput with respect to comfort, features and fit, as well as a standardized measurement system using a computer-controlled Load Carriage (CL) Simulator. The LC Simulator has been programmed to a walking cadence of 3 km/hr using computer controlled pneumatic actuators. Three pack assessment strategies were used to examine the effect of pack dynamics with respect to a standardized mannikin: a) strap force sensors on the shoulder straps and waist belt; b) pressure sensors under the shoulder and waist straps and lumbar pad; and, c) differences in motion between the pack and the person. The purpose of this portion of the study was to validate the measurement systems used in the LC Simulator under both static and dynamic conditions, and to conduct a sensitivity analysis of the biomechanical model used to evaluate shoulder and lumbar forces. In order to accomplish the first objective, independent measurement strategies were formed for each of the LC Simulator output measures. The second objectivge of validating the biomechanical model was initiated by developing a standardized jig for shoulder strap testing where strap forces, pressures, shoulder geometry and pack conditions could be evaluated independently.
