Fatigue Analysis of the Rotor Shaft on a High Speed Traction Motor

Abstract:

Rotor shaft is an important part in the high speed traction motor. In the process of the motor running，some rotor shaft may show the symptoms of fatigue crack，fracture and other issues．Therefore，it is essential to analyze its fatigue condition for these potential problems in the product design stage．In this paper，finite element analysis software NX. Nastran is used to analyzing the rotor shaft of traction motor from structural strength，fatigue strength and fatigue life respectively．The fatigue damage area and dangerous zone of the rotor shaft as well as its fatigue life can be predicted according to the simulation results，and which could provide a critical review for the following study and structural design of the traction motor．
