Abstract�� The characteristic of space heat exchange was introduced for extravehicular spacesuit, the heat transfer process of the thermal system was analyzed among space environment, extravehicular spacesuit and the human body, and with the help of Visual C++ 6.0 and OpenGL a three-dimension human body model was developed in which the computing results about human body surface temperature were displayed. Simulation technique of the thermal system was established with the combination of human body thermal regulation model, it was used to analyze human body thermal state under various metabolic rate, passive thermal protection conditions of spacesuit and the control of liquid-cooling and ventilation system. So the technique was used to determine the work conditions about liquid-cooling and ventilation system to assure the human bodies comfort state. Simulation results were verified by the thermal Manikin test, this issue is of important value in engineering application.
Keywords�� extravehicular spacesuit   simulation technique   EVA   human body thermal regulation model   metabolic level
