【Abstract】 The finite element model is established for rotor system supported by angular contact ball bearings,and corresponding software is developed for analyzing vibration frequency of the system.The static frequency is calculated based on the finite element model,and the influence of rotating speed on the dynamic frequency and characteristics of frequency and amplitude is analyzed,coinciding with result of the actual experiment.The result indicate that frequency at the biggest peak value of frequency signal is related to the static frequency of the system.更多还原
