Abstract
In this study, a contacting model was investigated for interference fit shaft–hub system (rotor system) on rotational speed 30000 r/min by finite element method (FEM) which gives more complete and accurate results than the traditional method. 2-d and 3-d FEM contacting models were established first; then the stress distribution and contact state of rotor system which containing four interference fit couples were analyzed with the contacting FEM model system while the rotor system rotates on 30,000r/min. Finally, an optimal design of shrink range of the rotor system above was debated.
