【Abstract】 Objective To simulate the water environment during floating status after astronauts returned and splashed down on the sea because of space capsule emergency in the launching stage. Method Environmental temperature in the laboratory and water-temperature in the tank were auto-controlled individually according to heat charge calculation. To meet the need of maintaining the uniformity of water-temperature, the structure of the water circulation pipeline was specially designed to increase thread-conflux and laminar flow effect. Result It was proved that the experimental system satisfied the requirements for medical research and evaluation by its high precision and uniformity which even exceeded the design requirements. After acceptance, its performance was further proved in the field experiment of “the medical evaluation of the soak and cold resisting garment”. Conclusion The equipment provides satisfactory experimental condition for medical evaluation of the space suit used in the “ Shenzhou ” space capsule and simulated the low-temperature water environment for studies of human reaction in the floating status and medical evaluation of relative products in the area of aerospace.更多还原
