作者介绍了作为旋转机械诊断的有力工具的循环平稳过程理论。结果表明，众所周知的同步平均方法是一阶循环平稳的表达式，由二阶循环平稳发出的谱相关函数是早期诊断旋转机械故障的有效参数。此外，还证明了在齿轮系统上测量的振动信号具有二阶循环平稳性。在齿轮剥落早期诊断中的应用证明了该参数的有效性。(C) 2000年学术出版社。
The payer introduces the theory of cyclostationary processes as a powerful tool for the diagnosis of rotating machines. It is shown that the well-known synchronised averaging method is the expression of cyclostationarity at the first order, and that the spectral correlation function issued from the second-order cyclostationarity is an efficient parameter for the early diagnosis of faults in rotating machines. Moreover, it is shown that vibration signals measured on gear systems display second-order cyclostationarity. Application in early diagnosis of spalling in gear teeth demonstrates the power of this new parameter. (C) 2000 Academic Press.
