Aerospace Instrument-Making Annotation << Back Disturbing moments in a floating gyroscope with an elastic body of the float, possessing rigidity ribs, on a vibrating foundation L.I. Mogilevich, V.S. Popov The investigation of vibrating disturbing moments influencing the gyro unit of the floating gyroscope, conditioned by the interaction of supporting layer of liquid and the elastic body of the float with rigidity ribs on the basis of settling and solving the problems of hydroelasticity was carried out. The authors showed the positive influence of the rigidity ribs of a floating gyroscope under circular vibration demonstrated in lowering instrument zero drift; under a linear vibration appears a negative influence which causes the growth of drift’s speed of an instrument zero under low frequencies.
