| 摘 要： | 以某型发动机压气机四、六级叶片为例，采用有限元数值计算方法，探讨了固支状态对叶片自振频率计算值的影响。得到的结论是：对于叶片的前七阶振动，通常的叶片固支状态对叶片自振频率计算值几乎没有影响。

| Abstract: | The fourth and sixth stages of a mode of aero-engine compressor blades are taken as examples, and effect of fixed state on calculated result of compressor blade intrinsic vibration frequency is studied by applying a finite element method. The conclusion shows that the calculated results of blade intrinsic vibration frequencies bear no relation to the common fix states for the first seven-order blade vibration. |

| Keywords: | fixed state compressor blade intrinsic vibration frequency effect |
