摘要
:在研究调制边频结构的形成及其数学描述的基础上 ,提出二次 FFT分析边频特征识别方法 ,为含齿轮、轴承类基础件的旋转机械故障诊断提出了有效的工具 。
In this paper, the Fourierformation of side band and its mathematical description are researched. Based on it, the advanced side band feature recognition method of Further Fourier Transform Analysis is proposed, which provides an effective tool for rotary machinery failure vibration diagnosis. Finally, examples are used to illustrate the theoretical significance and the practical value of the above mentioned method.
