Abstract: Based on the modeling theory of rated temperature prediction model, this paper summarizes the common rated temperature prediction models, concludes the related factors that affect the prediction results of rated temperature, summarizes the research progress of environmental adaptability prediction of coldweather gear, and points out the limitations of the commonly used prediction models in related research and application. On the basis of that, the paper puts forward the particularity and optimization method of the rated temperature prediction model in the environmental adaptability research of cold-weather gear. The optimization of the rated temperature prediction model for future cold-weather gear can focus on four aspects: the thermal resistance type of the garment, the environmental parameters, the assumed condition of the model, and the difference between the human body’s physiological heat balance and psychological comfort, so as to provide a reference for more accurate evaluation of the environmental adaptability of coldweather gear.

Key words: cold-weather gear; heat balance equation; rated temperature; ASTM F2732
