Modeling and Analysis of Heat Conduction Model of Clothing for High Temperature Operation

基于傅里叶热传导定律构建恒定高温环境下防护服热传导模型,并采用有限差分法分析了不同时间温度分布特征;通过设置边界条件,引入遗传算法对单层织物材料厚度最优质进行求解;通过多目标回归方法实现多个织物层的最优厚度求解.研究结果可为高温作业专用服装设计提供参考.

Working on high temperature environment, when the temperature of the environment reaches a certain height, special thermal protective clothing was needed to isolate the high temperature environment, which were important individual protective equipment.Based on the Fourier’s law of heat conduction, the heat conduction model of protective clothing under constant high temperature environment was constructed.The characteristics of temperature distribution at different time were analyzed by finite difference method. By setting boundary conditions, genetic algorithm was introduced to solve the best thickness of single-layer fabric.The optimal thickness of multiple fabric layers was solved by multi-objective regression method.The research conclusion provided reference for the high temperature operation special clothing design.
