摘要: 针对高温炎热天气佩戴防暴头盔给官兵头面部带来的严重积热问题,基于真人头部CT影像数据和《GA294-2012防暴头盔》标准构建了人体头部和防暴头盔的三维几何模型;选取经典Pennes生物传热方程作为控制方程,建立了“头-防暴头盔”的传热模型,在ANSYS-Fluent软件平台下对“头-防暴头盔”系统的三维热学过程进行了数值模拟,在此基础上分析了头盔壳体材料、头盔缓冲层材料、通风孔设计对头面部积热的影响。结果表明:PC(聚碳酸酯),ABS(丙烯腈-丁二烯-苯乙烯)和HDPE(低压聚乙烯) 3种壳体材料下的头面部温度分布差异较小;缓冲层材料的导热系数对头面部温度分布影响较大;在防暴头盔上设计通风孔可有效降低头面部温度。

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.
