| 摘 要： | 为了提高故障诊断正确率,通过将倒谱和1(1/2)维谱相结合定义了倒1(1/2)维谱。1(1/2)维谱能够消除高斯噪声,倒谱能够减少谱图中的虚假谱峰,但噪声对倒谱分析的结果具有较大的影响。倒1(1/2)维谱则可以结合1(1/2)维谱和倒谱的优点。通过将1(1/2)维谱、倒谱和倒1(1/2)维谱分别应用于溢流阀故障诊断实验,结果表明,倒1(1/2)维谱可以取得较好的故障诊断效果。

Study and AppliCation of 1 12 SpeCtrum and lts Cepstrum in Fault Diagnosis |

| Abstract: | In order to improve the correct rate of fault diagnosis,through combining cepstrum and 1 12 dimension spectrum,1 12 dimension cepstrum was defined. Theoretically,1 12 dimension spectrum,can suppress the Gauss noise completely,cepstrum can reduce false peaks in spectra,but the noise has a significant influence on the cepstrum analysis results. 1 12 cepstrum,can combine with the advantages of 1 12 dimension spectrum and cepstrum. Through the application of 1 12 dimension spectrum,cepstrum and 1 12 cepstrum in the overflow valve fault diagnosis,the results show that the 1 12 cepstrum can obtain a better effection. |
