Development in vibration signal analysis and processing methods 平稳和非平稳振动信号的若干处理方法及发展
2.
The nonstationary vibration sources that are mutually independent can be effectively identified by using the nonstationary blind source separation method from the multi - channel fault vibration signals 对于多通道的设备故障振动信号，应用非平稳信号的盲源分离算法，可以有效地提取各自独立的非平稳振动源，从而可以准确地进行机械故障诊断。
