Development and exploration of space weightlessness physiological effect tester

Aiming at the on orbit medical test requirements of the physiological effect of weightlessness faced by the astronaut space station, a space weightlessness physiological effect tester is developed, and its working principle and functional requirements are briefly introduced. Through the transformation, design and development of the existing instrument, its reliability and technical indexes are further improved. The thermal simulation and spectral test of the instrument are carried out, and the Raman spectra of Dinitrobenzoic acid and Iceland spar are tested. The detection indexes meet the requirements of on orbit test of aerospace medicine. Finally, the research and development of space test instruments in the future are prospected.
