Dynamic Performance Analysis on the Bearing-double Rotors System

Based on the pseudostatic analysis of rolling bearing, the bearing -double rotors system mathematical model is established. by means of integer transfer matrix method and finite element method, the system critical speeds and unbalance responses are analyzed, when the working speed is far away the system critical speeds, the transverse flexion stiffness of double rotor-bearing system is good. The results show that the dynamic behavior of simulation analysis is coincided with the realistic case. The analyzing software could anticipate reasonably the dynamic response of double rotors system in specific case, and draw the using range of working radial play of roller bearing on the condition of meeting mainframe supporting rigidity.
