Analysis of Electrostatic Suspension Kinematic Characteristics of Hollow Be Rotor

Abstract:

The hollow Be rotor is a spherical rotor with high accuracy, it has been grinded by the four-shaft-ball lapping machine. The rotor is a hollow sphere with non-uniform wall structure and there are errors between geometric center and mass center. Analyze the affect of eccentric distance and harmonic coefficients to the working condition of the rotor, establish the kinematic balance equation of rotor that is solved by Matlab software, and draw the rotor motion law with the change of time. The results indicate that with the decrease of eccentric distance of the rotor, the influence of damped motion decrease significantly. The influence on the damped motion of the rotor can be negligible when the eccentric distance is less than or equal to 0.051μm. The larger the harmonic coefficients, the faster the rotor attenuate.
