Strength analysis of motor shaft based on ABAQUS

Focusing on the situation of the motor shaft breaking in the work, using finite element software ABAQUS, considering the coupling effect of interference fit, working load, and eccentric load, the strength analysis of the motor shaft is carried out. The results show that the interference fit will cause the stress concentration of the motor shaft, and the stress safety factor of the motor shaft under the working load can meet the use demand, while the eccentric load will significantly change the stress distribution of the motor shaft and reduce its safety factor. The variation of assembly interference and eccentric load will significantly affect the stress distribution of motor shaft.
