METHOD AND SYSTEM FOR MASS MEASURING UNDER WEIGHTLESS CONDITIONS

摘要

The present invention relates to a method and a system for measuring mass under a microgravity environment. The system for measuring mass under a microgravity environment comprises: an electronic magnet; a platform where a sample to be measured is fixated, which includes a first permanent magnet at a position corresponding to the electronic magnet, and which horizontally moves along a moving guide by repulsive power of the electronic magnet and the first permanent magnet; a position sensor which senses that the platform passes a preset specific position; an actuating device which turns on/off the actuation of the electronic magnet; and a central controller which calculates current applied to move the electronic magnet to the specific position based on voltage received from the actuating device, and calculates the mass of the sample by substituting the current into Math Formula 1 below: Math Formula 1 m_t=I_t/I_s(m_s+m_p)-m_p In the above Math Formula 1, m_t indicates the mass of the sample, I_s indicates the current applied to the electronic magnet when measuring standard mass, m_s indicates the standard mass, and m_p indicates platform mass.
