Abstract: | |
In this paper, the stress and deformation of the sleeve and shaft after interference fit were investigated by finite element model. Effects of interference and sleeve's thickness on the stress and deformation of the sleeve were studied. The results show that the maximum von Mises stress, contact stress, shear stress and deformation of the sleeve appears on the two ends. The contact pressure distribution is W-shape. The maximum von Mises stress of the shaft appears in the center. The maximum von Mises stress, contact stress, shear stress and deformation of the sleeve increase with the increasing of the interference. The maximum contact stress and shear stress increase with the increasing of the wall thickness, but the deformation decreases. With the increasing of the wall thickness, von Mises stress in the middle part of the sleeve decreases, but the stresses on the two ends increase. |
