摘要: 为了研究某型抗荷服在不同环境条件下的热防护性能,在分析抗荷服传热传质特点的基础上对该服装的不同节段分别建立不同的服装传热模型,再将人体热调节模型和服装模型结合起来模拟不同环境条件下人体着装的动态仿真,得到人体各节段皮肤温度、人体平均温度、核心温度以及出汗量等,计算出飞行员综合热应激指数,并进行实验验证.最后利用所建模型分析服装热阻及透湿指数对人体热负荷的影响.Abstract: To study the thermal performance of an antigravity suit, the thermal system simulation modal was build among human body, antigravity suit and environment. The suit was divided into 15 segments, each segment has different thermal resistance and gas permeability. The system heat and mass transfer process were analyzed according to suit characteristic. This modal can simulate human body skin temperature, core temperature and sweat. The combined index of heat stress(CIHS) was calculated with these parameter to evaluating human body hot load. Experiments were designated to validate the modal calculation results. The differences between experimental and calculating results is small. At last, influences of the suit thermal resistance and impermeability index to body hot load ware analyzed with the modal built above.
