The Study of the Effect of the Blade’s Aspect Ratio and Thickness on Rotating Vibration

Abstract:

Study the effect of the blade’s aspect ratio and thickness on rotating vibration according as modulating frequency can reduce the resonance vibration of the blades. Research the modal analysis of the blades of the aero-engine. Apply the software of a finite element method (FEM) to simplify calculating process. Establish three finite element models of the blade. Calculate and analyze the natural frequency and mode of each blade. Analyze the local resonance which is caused by the wake flow exciting force in the different conditions of the engine. The structure of the blades should be right for the engine conditions which make the vibration frequency of the blades out of the resonance vibration scope.
