| Abstract: | In order to make the aeroengine rotor interference spigot with heating assembly correctly, it is necessary to select the appropriate pressing force. By using the finite element method, the steady, transient thermal and dynamic analysis of the interference spigot are carried out, and the precise change trend of the temperature field, contact pressure and friction force in time domain are obtained, the results provide a reference for the reasonable selection of the interference spigot pressing force. |
