Abstract:

In magnetically suspended high-speed rotor, the strong gyroscopic effect causes radial rotations of the rotor coupled and leads to precession and nutation, which exhibits different stabilities at different rotor speeds and influences rotor system stability primarily. For direct-viewing and robust stability design, a new stability analysis method based on two-frequency Bode diagram is proposed to discriminate precession and nutation stability of magnetically suspended symmetric high-speed rotor.
