In this paper, one shrouded impeller in some centrifugal compressor is selected to do some detailed finite element analysis based on nonlinear contact theory. Considering the rotating inertial load, the residual interference between the shaft and impeller hole is obtained. Then thorough researches about relationships among the residual interference, the equivalent stress, contact stress and transmission torque are carried out. At last, according to the transmission torque requirement, some advices are brought up for rotating-loose estimate and interference determination.
