服装局部热阻与总热阻的动静态关系及其模型

为研究人体在静止站立和行走时服装局部热阻之间的比例关系，以及真人测试和假人测试服装总热阻之间的关系，利用热流计法对人体设定的10个部位测定热流密度，计算得到服装局部的热阻，通过面积系数计算得到站立和和行走状态的服装总热阻，然后对不同测试条件下各部位服装的动静态热阻进行线性拟合，得到拟合斜率，并探讨 了不同状态对服装热阻的影响。结果显示：动态热阻明显低于静态热阻，10个部位动静态模拟斜率依次为：0.72，0.75，0.87，0.74，0.75，0.83，0.82，0.95，0.61，0.64；斜率小于或等于0.76的部位受运动的影响显著。最后得到真人测试的静态热阻和动态热阻，真人和假人测试得到的静态热阻以及动态热阻之间的数字模型。

Relationship between static and dynamic thermal insulation of local or whole body and its model

In order to study the relationship of local thermal insulation between standing and walking states and the relationship of the total thermal insulation between the human testing and thermal manikin testing, the heat flow density of the 10 parts of human body were measured by the heat flow meter method. Firstly,the thermal insulation of standing and walking were calcuated by the area coefficient. The average value of the radio of four ensembles was calculated as the final radio of thermal insulation. Secondly, the dynamic and static thermal insulationof each part were linearly fitted.The relationship between the thermal resistance ratio and the slope of the fitted straight line was evaluated. The results show that the dynamic thermal resistance is significantly lower than the static thermal resistance, and the radio of dynamic and static follows by 0.72,0.75,0.87,0.74,0.75,0.83,0.82,0.95,0.61,0.64. The parts that the slope smaller than or equal to0.76 is significantly affected by the moving. Finally, the digital model between staticand dynamic thermal insulation of the human testing, the relationship between the human testing and thermal manikin testing under dynamic condition were obtained.
