As a kind of protective equipment that can protect the human body from high temperature damage, the special design of high temperature protective clothing is the key point and hotspot in thermal research. Based on the theory of heat transfer, a simulation optimization model based on generalized cellular automata was established in this paper. The numerical solution of the parameters of the high temperature protective clothing was obtained by using the method of loop traversal. The experimental results showed that the optimal thickness of the second layer was 10.3 mm. The sensitivity analysis results showed that the surface temperature of the human skin changed within 1°C when the thickness of the second layer changed between 0.2 mm and the stability was good.
