| Abstract: | The coupled vibration characteristics of a typical two-stage compressor blade-disk system were simulated based on ANSYS software. The characteristics of the system modal were analyzed by using a finite element modeling method of two-stage bladedisk system, and compared with the single stage blade-disk system. The .vibration characteristics of two-stage blade disk system were assessed by using strain energy theory. |

| Keywords: | blade-disk（blisk） system coupled vibration strain energy |
