Clothing for high-temperature work and its model design method

Abstract

The invention discloses a high-temperature operation garment and a model design method thereof, belonging to the field of high-temperature operation clothing. A high-temperature work clothing and its model design method are analyzed in four steps. First, the problem is analyzed to determine the need to distribute and establish a four-layer heat conduction model, a single-objective optimization decision-making model, and a dual-objective optimization decision-making model. Through the four-layer heat conduction model and each Based on the initial conditions, boundary conditions and interface conditions of the layer, the time relationship model of body surface temperature is obtained, combined with computer software and language programming, the relevant parameters of the system in different situations are solved, so as to determine the optimal thickness of a certain fabric layer, making the thermal protective clothing It can meet the needs of different high-temperature working environments, and at the same time achieve the purpose of reducing research and development costs and shortening the research and development cycle.

Description

technical field

[0001] The invention relates to the field of high-temperature work clothing, in particular to a high-temperature work clothing and a model design method thereof. Background technique

[0002] Clothes, food, housing and transportation are the most basic needs of human beings, and clothing occupies the primary position. It is an intermediate between people and the environment, acting as the second skin of the human body. Nowadays, with the improvement of living standards, people's requirements for clothing are getting higher and higher, and the requirements for clothing in different environments are also getting higher and higher, especially in high temperature;

[0003] People who work in a hot environment are under greater pressure than those who work in an ordinary environment. Therefore, special clothing should be worn when completing high-temperature operations, and the staff can be protected under high-temperature or ultra-high temperature conditions to a...
