摘要

摘要: 分析了舱外航天服空间换热的特点,对"空间环境-舱外航天服-人体"热系统进行了传热分析,利用Visual C++ 6.0及OpenGL技术进行了三维人体模型的构造,对人体体表温度的计算结果进行了三维图形显示.结合人体热调节模型建立了"空间环境-舱外航天服-人体"热系统仿真技术,分析了航天员在不同代谢模式、被动热防护状态及液冷、通风系统控制情况下的热状态,确定了各代谢活动水平下航天员达到舒适状态时液冷、通风系统的工作条件,利用暖体假人试验结果对系统仿真进行了验证,结果表明二者吻合很好,本项目具有很好的工程应用价值.

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.
