Abstract

In this paper, based on finite element (FE) software MSC.Marc, a two-dimensional nonlinear thermo-mechanical coupled model is established to investigate the hot shrink-fit process for the reactor coolant pump rotor-can. By using this model, the limited time and temperature evolution for hot shrink-fit process are calculated. The residual stress and contact force after shrink-fit are analyzed. The results indicates hot shrink-fit time, the contact force and residual stress decreased with the increase of interference. For the sake of expanding the shrink-fit limit time and improving success ratio, a kind of insulation layer is designed. With the increasing of thickness of insulation layer, the limit time for hot shrink-fit is linear increased. The results show the necessary time for the shrink-fit processing is increased to 85s when the thickness of insulation layer is 2.00mm.
