摘　　要：利用ANSYS有限元软件进行仿真,研究了典型发动机2级压气机叶片-轮盘系统的耦合振动特性;采用1种2级叶盘系统的有限元建模方法,分析了该系统的模态特性并与单级叶盘系统的进行比较;应用应变能理论定量评价了2级叶盘系统振动特性。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.
