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.
