Abstract
This paper designs a mathematical model to determine the heat protective performance of special clothing for high-temperature operation. This is an important protective measure for high-temperature operation. Based on the known material parameters of special clothing, experimental data are obtained by simulating the actual situation and fitted with MATLAB software. A mathematical model to determine the heat protective performance of special clothing for high-temperature operation is established, which solves the issue of determining the optimal thickness of special clothing for high-temperature operation in certain conditions.
