摘要 为提高工人高温作业的安全性和生产效率,本文提出一种工业高温作业服装设计。本文首先根据对90分钟测试的皮肤温度数据,结合指数模型与高斯模型,拟合出皮肤温度的时间函数;随后建立了从I层左侧到假人皮肤外侧的三层热传导模型,即环境温度通过热防护服到假人皮肤的抛物型齐次偏微分方程组.采用Crank-Nicolson差分法进行求解,计算得到各层表面的温度分布。在此基础上,结合稳态条件下材料热流密度,通过优化模型设计出不同环境温度和皮肤表面温度条件下的最优防护服厚度,对工业生产中具有一定的理论指导意义。 In order to improve the safety and production efficiency of workers working at high temperature, this paper presents a garment design for industrial working at high temperature. In this paper, the time function of skin temperature was firstly fitted based on the skin temperature data measured in 90 minutes and the combination of exponential model and gaussian model. Then, a three-layer heat conduction model from the left side of layer I to the outside of the skin of the dummy was established, that is, parabolic homogeneous partial differential equations of ambient temperature to the skin of the dummy through the thermal protective clothing were developed. On this basis, combined with the material heat flux under steady-state conditions, the optimal thickness of protective clothing under different ambient temperatures and skin surface temperatures was designed through an optimization model, which has certain theoretical significance for industrial production.
