多层热防护服最优设计

论文运用数学的方法研究热防护服装并确定其最优厚度。首先建立热传导模型,并利用有限差分方法得到热传导方程的离散格式,之后根据热源温度和最内层的人体平均温度及服装材料的参数值,计算出各层初始条件。之后,利用MATLAB编程及热传导方程的离散格式得到各层的温度分布。最后,利用二分法,得到热防护服的最优厚度。

Optimal Design of Multi-Layer Thermal Protective Clothing

This paper uses mathematical method to study the thermal protective clothing and determine its optimal thickness.Firstly,the heat conduction model is established,and the discrete format of the heat conduction equation is obtained by finite difference method.Then,the initial conditions of each layer are calculated according to the heat source temperature and the average temperature of the innermost layer of human body and the parameters of the clothing material.Then,the temperature distribution of each layer is obtained by MATLAB programming and the discrete format of the heat conduction equation.Finally,the optimal thickness of thermal protective clothing is obtained by dichotomy.
