| 摘 要： | 以某型航空发动机压气机第六级叶片为例，研究了温度对叶片振动频率的影响。发现由于温度的升高导致了材料弹性模量的下降，而弹性模量的下降又导致了叶片在发动机一定的转速范围内，除一阶振动外，其余各阶振动的动频均小于静频，因此与通常的工程处理方法不同，研究压气机叶片的动频时，应考虑温度的影响。

| Abstract: | The 6th stage blade in aero-engine compressor is taken as an example, the temperature effect on the blade vibration frequency blade is investigated. It is found that the elastic modulus of material decreases due to the increasing temperature, as a result, the vibration frequencies of the rotation blade are, except that of first bending vibration, lower than that of the static ones when the revolutions of aero-engine is slow, so effect the temperature ought to be considered in the vibration frequency research of compressor blade. |

| Keywords: | compressor blade vibration frequency static frequency temperature effect. |
