Article Description

According to the structure of the micro-gyroscope with a ball-disk rotor, the corresponding Reynolds equation is solved by using the motion equation, continuity equation, and state equation. The damping coefficients of axial vibration, radial vibration, and rotation around the Z axis are derived theoretically. The damping theoretical model of the micro-gyroscope is constructed to analyze the gas film damping and oil film damping of the ball-disk rotor in three degrees of freedom motion.
