Research On Balance Spherical Hollow Be Rotor For Electrostatic Suspended Gyroscope

The hollow spherical Be rotor is the key part of the Electrostatic Suspended Gyroscope. Whether its quality is good or not and the precise degree would immediate affect electrostatic gyro’s operating performance and precision. The high quality, the high accuracy sphere hollow rotor is mainly refers to under the high speed revolving active status, can guarantee that has the small quality unbalancedness and roundness error. And, the quality unbalancedness of sphere hollow Be rotor will cause the top’s drifting and its rotational speed weakens, thus influence electrostatic gyro’s long time navigation accuracy. Therefore the most important key indicator of appraising the sphere hollow rotor precision is quality unbalancedness. So we must carry on the mass balancing to the sphere hollow Be rotor.The essential target is to carriy out the sphere hollow Be rotor balancing technique research comprehensively, systematically and profoundly, then further enriched and consummated the sphere hollow Be rotor balancing technique from the theory and the practice. The research content primary includes: The rigid sphere hollow Be rotor static unbalanced and its algorithm; the rigid sphere hollow Be rotor static unbalance analysis; the rigid sphere hollow Be rotor dynamic unbalance analysis; the flexible sphere hollow Be rotor dynamic unbalance analysis; the sphere hollow Be rotor static unbalance amount survey and revision; the sphere hollow Be rotor static balance data regression analysis; the unbalance amount and roundness error hasten slightly.Through the above research content, preliminarily established the sphere hollow Be rotor balancing technique system initially, filled the flexible sphere hollow Be rotor’s dynamic unbalanced, the sphere hollow Be rotor’s static balance data regression analysis, and the equilibrium amount and roundness error hastens slightly, etc.
