DEVICE DETERMINING MASS OF OBJECT Russian patent published in 1997 - IPC

FIELD: determination of mass of objects under conditions of zero gravity. SUBSTANCE: device determining mass of objects has vibration exciter manufactured in the form of two electromagnets fixed on bracket in symmetry to ferromagnetic plate anchored on structure with the help of clamp and electrically coupled to excitation amplifier which is connected to outputs of induction pickup and source of electric current, case with covers and mechanisms to move the latter located in case, rotation drive kinematically coupled to mobile armature supported in axially positioned bearings in covers and fabricated in the form of rod with supporting platform where rests for springs are made. Each spring is put on rod and rests with one end against supporting platform and with the other one - against cover. Rod is coupled with one end to driving half-clutch of drive, its other end carries holder with tested object. Vibration exciters are integrated in at least three units of electromagnets in pairs. Springs are crimped in advance and bearings are made from material with low friction factor. EFFECT: simplified design, increased functional reliability and stability. 2 dwg
