Abstract:
      HT5SS]:This paper investigates the axial\|flexural vibrations of the rotating blade with the consideration of the coupling of rigid body motion and elastic motion. By means of finite element method, the paper derives the dynamic equations of discrete system and leads to gyroscopic characteristic value problem. The paper computes the natural frequencies of a certain rotating channel beam with different rotating speed, and discusses the influence of rotating speed on natural frequencies.
