Vibration Property Analysis of Turbocharger Blade 1999-01-1229

Free vibration of the blades of one radial-flow turbocharger is analyzed by the finite element method, and the natural frequencies and modes are obtained, the numerical results are in good agreement with the experimental ones. Resonant vibration of the compressor blade and turbine blade is analyzed respectively, then the resonance interference analysis of the blades is presented, the resonance occurrence probabilities of the blades at the rotating operation speed of the turbocharger is obtained, finally the working reliability of the blades is evaluated.
