摘　　要：为了探究舱外航天服人体舒适性与主动热控的关系,采用10名男性志愿者参加的人体舒适性实验方法,研究了舱外航天服液冷服入口水温对人体舒适性的影响。实验结果表明:随着运动负荷增加,人体热舒适需要更低的液冷服入口水温,航天服可通过液冷服入口水温调节改善高代谢状态下人体舒适性,但在低代谢状态下,当前的热控方案不能满足所有志愿者静息状态时的人体舒适性。按照研究结果提前预设液冷循环状态,可提高航天员舱外操作工效和人体舒适性维持效率。In order to explore the relationship between human body comfort of EVA(Extravehicular Activities)spacesuit and active thermal control,the experimental method for human body comfort of 10 male volunteers was adopted to study the effects of water temperature of the wearable Liquid Cool-ing Garment(LCG)on the human body comfort in EVA spacesuit.The experimental results showed that the human metabolism thermogenesis increased with the increase of the exercise load and lower water temperature was required for the human body comfort.The regulation of water temperature in EVA spacesuit LCG could satisfy the human body comfort in the condition of hyper-metabolism ther-mogenesis,but the current thermal control scheme of the EVA spacesuit could not completely satisfy all volunteers’body comfort in the condition of hypo-metabolism thermogenesis.According to the re-sults,preset the liquid cooling cycle state in advance can improve the astronaut’s extravehicular op-eration efficiency and maintenance efficiency of human comfort.
