| 英文摘要 | 提出了一种利用三谱对角切片分析溢流阀故障信号的方法。高阶谱理论上能完全消除高斯噪声的影响,本文由经过预处理的信号经过高阶谱分析后,可以得到三谱对角切片图,由图中可以获得正常信号与故障信号在切片图上的差异。试验结果表明利用高阶谱理论进行故障检测是可行的。; A method of overflow valve fault analysis based on high order spectrum was proposed in this thesis.High order spectrum can fully eliminate Gaussian noise theoretically.Via the high order spectrum analysis of preprocessed signal,the trispectrum diagonal slices can be obtained.through which the difference between normal and abnormal signals can be found.The experiment results indicate it is feasible to carry out fault analysis using high order spectrum.; 2008福建省重大专项课题(2008HZ0201) |
