| 摘 要： | 对引起航空发动机压气机高压转子叶片振动故障的原因进行了分析.指出压气机在某种非正常工作状态下产生的高声强噪声中所包含的高强度声波,是激起转子叶片共振或颤振的原因之一,通过理论分析和实验研究,得出了如下结论:当转子叶片在机械激振和气动激振作用下已处于高应力工作状态时,如果再叠加由声波激起的共振应力,就会导致裂纹甚至折断. |
| 关 键 词： | 航空发动机 转子叶片 声波激励 振动 试验 |

| Abstract: | The vibration faults of aero-engine high-pressure compressor rotor blade were analyzed.The high-intensity sound waves contained in the high-strength noise generated by the compressor in a non-normal working condition one of the reasons for rotor blade excitation resonance or flutter.By theoretical analysis and experimental verification,the following conclusions were obtained: If the high stress caused by mechanical excitation and aerodynamic excitation and the superposition of the resonance stress caused by... |
