The vibration of a rotating shaft fitted with a rotor at the critical speed when the restoring force of the shaft is a non-uniform and non-linear function of the displacement of the rotor is discussed. When the shaft has a soft spring characteristics or a hard spring characterieristics in all directions, the displacement of the rotor remains within a certain limit at the critical speed, but when the shaft has a soft spring characteristics in one direction and a hard spring characterisics in the direction perpendicular to the former, the displacement of the rotor increases indefinitely at the critical speed. Moreover the displacement of the rotor at the critical speed when the rotor is asymmetrical is discussed.
