The application that machine tool high speed turns and development, rotate speed of requirement main shaft rises. But part of series of machine tool main shaft is in production process, inevitable meeting pledges because of material asymmetry of inhomogenous, appearance, treatment is installed compound an error and bring about deviate of centre of gravity to rotate center, make the machine tool produces vibration and oscillatory power, cause machine tool noise, bearing to give out heat etc. Lift as rotate speed, lopsided the vibration that cause is added more intense. Be out of shape as a result of what arise when component of machine tool main shaft is rotational very small, calculate to simplify, reason inspects his to serve as the balance method of rigid rotor to handle. Inspect rotor very rigid body, and assume when the job, the runner shaft below effect of lopsided centrifugal force won't happen to be out of shape significantly. A lot of complex lopsided position of rigid rotor leave in these conditions for this, can simplify the department that it is force is lopsided will handle, can increase on two plane of aleatoric make choice of or subtract two equivalent at Ud1, make with the dynamic balancing force of Ud2 its are balanced. Rigid rotor dynamic balancing is low speed dynamic balancing commonly, the 1/3 that chooses the first critical rotate speed commonly is the following. Lopsided: ?
