From the basic theory of fracture mechanics and combining the fatigue mechanism of rotor crack propagation, energy theory and power relationship, the stress analysis and deformation of the rotor are discussed, and the acoustic emission mathematical model of the rotor crack propagation is deduced, which will provide the theoretical basis for the further study of the acoustic emission in the rotor crack fault detection.
