Comparison of human responses to prototype and standard uniforms using three different human simulation models: HSDA, Scenario(underline)J and Simulink2NM

摘要

The human thermal physiological responses of Soldiers in three new prototype clothing systems under development were compared to responses in the current standard duty uniform (STDU) with body armor (BA) and load bearing equipment (LBE) while engaged in the same activities and environments. The prototype uniforms in the comparison were the Scorpion A, Scorpion B, and Concept2OO5 (C2005). C2005 was evaluated with and without clothing ventilation provided by its battery powered fan. The comparisons also include the effects of the clothing system on the Soldier with and without chemical biological defense gear (CBD). The Soldier's responses were determined by simulation using 3 different well accepted thermo physiological computer models. The models: (1) USARIEM Heat Strain Decision Aid (HSDA version 7); (2) USARIEM SCENARIO(underline)J (version l.0b); and (3) Simulink 2 Node Model (SimuLink2NM), are described in the following Methods section.
