Study on the Parameters of High Temperature Heat Insulation Based on Nonlinear Optimization

根据一维热传导方程,把保持37℃恒温的模拟假人放入75℃的高温下,对隔热服厚度参数与假人体表温度进行分析,建立了简单实用的非线性的优化模型,并在其它温度条件下,当满足劳动者体表温度介于44℃到47℃的时长不超过5min的约束条件时,对数据采用Richardson差分形式分析,借助MATLAB对实测数据进行仿真,在百分之一的精度要求下,得出了不同工作时长下防护服厚度的最优取法,对不同温度要求下防热服的设计具有一定的参考价值。

According to the one-dimensional heat conduction equation,the simulated dummies with37℃constant temperature are put into the high temperature of75℃,and the parameters of the thickness of heat insulation suit and the surface temperature of the dummy are analyzed,so a simple and practical nonlinear optimization model is established.Under other temperature conditions,the data are analyzed by Richardson difference form when the surface temperature is between44℃and47℃for not more than5minutes,and the measured data are simulated by MATLAB.Under the precision requirement of1/1000,the thickness of protective clothing with different working hours is obtained.This method has certain reference value for the design of heat insulation suit under different temperature requirements.
