Numeric Analysis for Resonant Frequency of Rotating Blade

Abstract:

Article Preview

The paper implements numeric computation to analyze free vibration characteristics of rotating blade by the means of finite element method. The effects of rotate speed and temperature on the resonant frequency of blades are considered. The static frequency and the dynamic frequency under working speed for the room temperature and working temperature are calculated, and the various modes are obtained. The resonance analysis is given by Campbell graph in which shows the distribution of resonant points for resonant frequency and rotate speed under the different excitation.
