二次复合设计在航天服热生理学分析中的应用

Application of Combined Second Design in the Thermal Physiolocal Analysis of a Space Suit

为对航天服进行热工程生理学分析,实验选定向航天服通风的气源风温、风量、风湿以及人体活动状态等主要因素,运用二次复合设计法进行6人24人次实验设计。使用最小二乘法建立了本研究所需指标与作用因素间的数学模型的方法。方差分析使模型的计算结果准确可靠,符合人体热生理学变化规律。 无约束最优化,全局收敛性。

In order to investigate a space suit form the thermal physiological viewpoint, the second continued design was employed to arrange 6 subjects for 24 tests. By moans of LMS regression, established was the way by which mathematical models between thermal physiological indices and main influencing factors such as air ventilating parameters (air temperature, How rate and relative humidity) of the suit together with human metabolic states were obtained. Variance analysis attributed to the accuracy and reliability of the models which were reasonable in human physiological consideration.
