| 摘 要： | 通过爆震试验测得了爆震声音数据。对单次爆震的声音数据进行傅里叶变换发现,爆震声音数据中包含了与压力数据中同样的主频和多倍频,说明一直作为噪声处理的爆震声音数据可以用来辅助分析爆震发动机性能,对爆震分析和故障诊断起到积极作用。

| Abstract: | The detonation audio data were acquired by detonation test.The fourier transform was performed to the single detonation audio data.The results indicate that the detonation audio data contains the same primary frequency and multiple-frequency as those in the pressure data,which means that the detonation audio data can be used to help analyzing detonation engine performance and has a positive effect on detonation analysis and failure diagnosis. |
