Stress analysis of shrink fitted joints of solid shafts and three-dimensional photoelastic experiment

摘要

In this paper, shrink fitted jints of solid shaft and ring made of epoxide resin were assembled and photoelastic experiments were carried out. Isochromatic fringe patterns in the shrink fitted joint were measured using the three-dimensional stress freezing method. Then, the contact stress distributions in the shrink fitted joint of the ring and the solid shaft were analyzed using the finite element method. The three models, i.e., with slip, without slip and with partial slip at the interface were analyzed and the results were compared. The effects of chamfer at the edge of the interface and the material proerties of the ring (hollow cylinder) on the contact stress distributions were examined.
