Abstract

When the flexible rotor has obvious warping or static warping, the over-critical amplitude of the rotor will increase significantly. It is necessary to carry out dynamic balance work to reduce the critical speed amplitude of the rotor. The dynamic balance shows that the existence of warping changes the vibration characteristics of the rotor significantly. To clarify the causes of the above phenomena and optimize the dynamic balance effect of the warped rotor, a Jeffcott warped rotor model is established. Then, the influence of the initial warping on the rotor and the vibration response rule under the joint action of the initial warping and the unbalanced mass are obtained. Finally, a new method for the dynamic balance of the warped rotor is formed. The critical amplitude and operating speed amplitude both meet the limit requirements, and the normal operation of the rotor with large warping is achieved.
