摘　　要：暖体假人是以电热丝作为内热源来模拟人体散热的一种设备,主要用于测试服装热阻,对表面温度均匀性要求极高。为找出影响假人表面温度均匀性的主要因素,达到假人表面温度分布均匀的要求,提出假人表面电热丝的敷设方案和温度测试方案。通过对比实验,观察假人皮肤表面的温度分布规律。结果表明:电热丝的敷设间隔、假人皮肤的覆盖厚度以及侧面边界条件对假人表面温度均匀性都有不同程度的影响。Thermal manikin is equipped with heating wire which serves as internal heat source to simulate the human body heat dissipating,and mainly used for testing the thermal resistance of garments,whose surface temperature uniformity is critical.The aim of this study is to find out the main factors influencing the uniformity of the temperature on the surface of thermal manikin and how to meet the requirement of uniform distribution of the temperature.The arrangement of the heating wire and test method of the temperature are presented.Comparative experiments are conducted and temperature distribution rule on the surface of the thermal manikin is observed.The test results indicate that the laying interval of heating wire,thickness of thermal manikin′s skin cover,and the side boundary conditions on the surface all have influence on the temperature uniformity to different extents.
