摘要 穿戴高温防护服是防止人在高温作业环境中被灼伤的重要手段。本文对高温防护服传热过程进行分析,在合理简化假设的基础上将此过程转化为一维热传导问题,建立基于一维热传导方程的高温防护服温度分布模型,并确定初始条件、边界条件及耦合条件。为避免求解复杂的偏微分方程,本文采用有限差分法对偏微分方程进行求解。考虑到防护服的实用性及经济性,本文对防护服的厚度进行单目标优化,并采用变步长搜索法对单目标优化模型进行求解。 Wearing thermal protective clothing is an important means to prevent people from being burnt in high temperature working environment. In this paper, the heat transfer process of thermal protective clothing is analyzed. On the basis of reasonable simplifying assumptions, this process is transformed into one-dimensional heat conduction problem. The temperature distribution model of high temperature protective clothing based on one-dimensional heat conduction equation is established, and initial conditions and boundary conditions are determined. Coupling conditions. In order to avoid solving complex partial differential equations, the finite difference method is used to solve the partial differential equations. Considering the practicabili-ty and economy of protective clothing, this paper optimizes the thickness of protective clothing and solves the single objective optimization model by variable step search method.
