Abstract

In order to evaluate cold stress and injuries of hands, develop high-performance gloves, and improve work efficiency of first responders, from perspective of multi-segment and multi-layer modeling, hand was divided into 7 segments including thumb, index finger, middle finger, ring finger, little finger, palm and dorsum, and each segment included four layers which were skin, fat, muscle, and core layer. Then, a hand thermal response model was proposed to simulate skin temperature. Finally, simulations were compared with measurements in literature so as to validate prediction accuracy of the model. The results indicate it shows great accuracy in palm and dorsal skin temperature, and simulations are comparatively consistent with measurements with a maximum discrepancy of 3. 6 ℃ and 2. 4 ℃, respectively. Moreover, decrease rate in skin temperature of middle finger and ring finger are the highest, followed by thumb while index finger and little finger are the lowest. © 2020 China Safety Science Journal
