Vibration Analysis of Transmission Shafts Using Solid Models

Abstract:

Fatigue fracture of the intermediate shaft in a transmission was analyzed by finite element method.The solid model has advantages of centrifugal force and spin softening effects over beam models.The results show that the fatigue fracture of the shaft is mainly due to the torsional vibration,the stress stiffening and spin softening have strong influence on the bending vibration medes,and torsional vibration modes do not changed at different speeds.There is accounting for the effects by an adjustment of the stiffness matrix.By using of solid models,the vibration modes of the intermediate shaft were researched,then the model was optimized in order to avoid resonance.
