Abstract:
Compressor is an important part of aero engine. In the environment of high temperature and high pressure, compressor blade will suffer from several physical and chemical processes, such as centrifugal force, aerodynamic force vibration and oxidation. These processes will lead compressor blade to fatigue fracture, and at the same time, make negative effects on the engine's overall performance. Based on the software ANSYS15.0, we made strength analysis and modal analysis of compressor blade in this paper. As a result, we got its natural frequencies, relevant modal parameters and vibration mode cloud pictures. After analyzing the influence that centrifugal force made on modal parameters, we predicted the expected damage of the blade. Eventually the analysis results will provide the basis for overall performance evaluation, structural crack detection, fatigue life estimation and strength calculation of aircraft engine compressor.
Key words:    compressor blade    centrifugal load    the modal analysis    natural frequency    vibration performance
