    Abstract

  • In view of the looseness of bearing supports in rotor systems, the mathematical representation of bearing impact process was established based on the geometric characteristics of loose supports. The bearing force of the loose end was calculated by Lankarani-Nikaravesh model. By using Newton's law, the dynamic model of the rotor system with bearing support looseness was established. The Runge-Kutta method was adopted to solve the dynamic equations. The influences of the factors, such as looseness degree, and working speed and damping, on the dynamic performance of the rotor system with bearing support looseness were studied. The results showed that: when the support of the rotor system was loose, the odd frequencies, such as fs, 3fs and 5fs etc., could show up on its spectrum. Besides, the service life of the bearing could be significantly reduced by the increase of the bearing force and the frequency of load alternation caused by the looseness of the support. With the looseness being heavier, the accuracy of the rotor system in the looseness direction decreased gradually. The rotor system might become more unstable as the degree of looseness increased, the operating speed increased, and the system damping decreased. The research results can provide a reference for the fault analysis of the bearing support looseness. It also can be applied into the looseness diagnosis of bearing pedestal.
