Study on the Mechanical Essence of Gyro Characteristics

Abstract. Simplify the gyro rotor into a hollow disk, each particle in the disk circular motion around the z axis with High speed. At same time, it around y axis rotation follows the disc. That is, the disk does not rotation, but each particle in the rotor circular motion relative to the disk, at the same time, it rotate with the angular velocity ω follows the disc. On the basis of the simplified model, apply the knowledge on the synthetic movement of theoretical mechanics; research each particle acceleration in the gyro rotor. Then according to the Newton's law to analysis the force situation of each particle in the rotor, to reveal the mechanical essence of nutation and precession characteristics of the Gyro rotor. Then, according to the situation of the applied forces on each particle in the rotor, reveal mechanics essence of nutation and precession characteristics of the gyro. Characteristics of the Gyro After a high-speed free rotating gyroscope transient is disturbed, its axis deviation. But after the deviation from the axis of rotation for a period of time, the rotation shaft gradually returned to the pre disturbance location. If applying a couple in a free rotating gyro rotor, not as people imagine, the rotor will produce rotation around perpendicular vectors applied couple axis. Above two phenomena known as the nutation and precession are strange. However, how it happened? What i
