Abstract

Abstract: Aiming at the serious heat accumulation problem to soldiers’ head and face while wearing anti-riot helmets in high temperatures, a 3D model of human head and an anti-riot helmet were established based on CT image data and GA294-2012 Standard of Anti-riot Helmet. The Pennes bio-heat transfer equation was chosen as the control equation, then a "head-helmet" heat transfer model was built. On the platform of ANSYS-Fluent software, the three-dimensional thermal process of "head-helmet" system were numerically simulated. And on the basis the influence brought from anti-riot helmet shell material, buffer layer material and vent hole to head facial heat accumulation were analyzed. The results show that the diversity of head and face’s temperature distribution is not obvious among PC, ABS and HDPE shell material, while the thermal conductivity of buffer layer material makes great influence on head and face’s temperature distribution. The head facial temperature can be effectively reduced when vent holes are devised on anti-riot helmet.
