Abstract
The fatigue life prediction method of a low pressure turbine shaft of the turbojet engine is presented. According to working conditions and assembled conditions of the turbojet engine, load types, load values and constraints of the turbine shaft are analyzed. ANSYS software is employed to simulate actual working conditions to obtain stress-strain distributions of the low pressure turbine shaft. Finally, based on stress-strain curves and surface quality, the fatigue life of the low-pressure turbine shaft is calculated with the modified local stress-strain method and the linear cumulative fatigue damage model.
