Description

technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to a ground calibration device and method for an on-orbit human mass measuring instrument. Background technique [0002] Aiming at the development of equipment for human body mass measurement using Newton's second law small-stroke mass measurement technology in the microgravity environment of the space station, it is convenient to measure the human body mass in the microgravity environment. The human body mass measurement system in a simulated microgravity environment includes an on-orbit human body mass measuring instrument, a human body pose fixing device and a ground microgravity environment simulation device. The on-orbit human body mass measuring instrument is a human body mass measuring device used in a microgravity environment. In order to complete the measurement and calibration of the device, it is necessary to simulate the weightlessness state in the ground ...

AI Technical Summary

Problems solved by technology

Most of the existing human body posture fixing devices adopt seat type, folding posture fixing link type, etc., but the above fixing methods have disadvantages such as large machining error, insufficient connection parts, and high requirements for the operation of the human body under test.

The existing ground microgravity environment simulation methods usually use drop tower / pipe vacuum, sounding rocket, aircraft parabola or air / magnetic levitation methods, but the weightlessness environment simulated by the above technologies has short duration, high cost, and unsatisfactory stability. Calibration required and expensive
