| Abstract: | Due to the turbocharger blade vibration, the phenomenon of leaf damage often occurs. By using three-dimensional CAD mod-eling software, the model of exhaust gas turbocharger turbine Impeller was set up. By using finite element analysis software, the respective vi-bration modal was analyzed. The resonance frequency was identified,which prorided a theoretical basis for the optimal design of the impeller. |
