< jats: p>本文提出了一种数字信号处理技术，用于从振动信号的平均值计算齿轮啮合振动的振幅和相位调制，并应用于疲劳裂纹等局部缺陷的早期检测。确认了相位调制在缺陷检测中的重要性。
< jats: p> A digital signal processing technique is proposed for calculating the amplitude and phase modulation of the tooth meshing vibration of a gear from the signal average of the vibration with application to the early detection of local defects such as fatigue cracks. The importance of phase modulation in the detection of defects is confirmed.
