| Abstract: | ABAQUS finite element analysis software is used to analyze the static strength and vibration characteristics of engine turbine blade.The stress and displacement distribution nephogram of the turbine blade is obtained.The reliability of the static strength of the turbine blade is verified.The natural frequencies and vibration modes of the turbine blades are obtained,the Campbell resonance curve is drawn,the resonance margin of the turbine blades under various operating conditions is calculated,and the possibility of the resonance is analyzed.Based on the simulation results of static strength and vibration characteristics,some suggestions on turbine blade maintenance and engine test are put forward. |
