高温服装热度分布的研究

Research on heat distribution of high temperature garment

在高温环境下,为避免灼伤,穿专用服装对人身安全至关重要。首先,文章利用Matlab绘制出温度变化图,获得其变化规律;其次,根据密度等专用服装材料的参数值,建立傅里叶热传导方程模型;再次,利用抛物型方程的差分解法以及对温度分布条件进行离散化,求出方程优化结果;最后,得到I^IV层温度分布的离散化函数,并得出结论:颜色区域越深,表示温度越高。以此帮助更好地设计高温专用服装。

In high temperature environment,in order to avoid burns,wearing special clothing is important to personal safety.First of all,the paper uses Matlab to draw the temperature change chart and get its change rule.Secondly,the Fourier heat conduction equation model is established according to the parameter values of special clothing materials such as density.Secondly,using the differential solution of parabolic equation and discretization of temperature distribution conditions,the optimization results of equations are obtained.Finally,the discretization function of the temperature distribution of I^IV layer is obtained,and it is concluded that the deeper the color area is,the higher the temperature is.This helps to better design special high-temperature clothing.
