| Abstract: | A mathematical model of rotor and stator is given. A calculation method is established to calculate the dynamic response of engines mounting points by using the measured dynamic stiffness of the mounting points. Both the dynamic response of rotor stator system and the transfer function between main supports and mounting points can be calculated simultaneously. Finally, a certain type of double spool aeroengine is taken as an example. |

| Keywords: | aeroengine steady state response measurement of dynamic stiffness |
