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。
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.
