In order to study the temperature distribution law of thermal protective clothing and skin under the action of low radiation heat load,the fabric layer thermal analysis was conducted.Four layers of fabric including outer layer,waterproof breathable layer,thermal-protective layer comfort layer and skin geometry model were built with finite element software,and the overall temperature prediction was made.Firstly,a single-layer fabric model was established according to the fabric parameter,and reliability of the model was verified.The skin model was established by the real human body,and the accuracy of the model was verified by the temperature distribution of each skin layer.Finally,a geometric model of multi-layer fabric-air layer-skin integral system of thermal protective clothing was established to study the heat transfer of fabric-air-skin and predict the temperature of fabric and human body at different ambient temperatures.It is considered that the model can accurately show the temperature distribution at different locations,which provides a certain reasonability.
