中文摘要:对调相信号进行解调,提取相位调制信号,可得到扭振信息。用最大熵谱检测扭转转频的二次分量大小和变化,对转轴组件的裂纹进行诊断。
外文摘要:The phase-composed signal was decomposed,from it extracted the phase-modulated signal and can get the wrest vibration signal.The maximum spectrum was used to test the number and the change of the sec- ond component in the wrest rotating frequency.It was monitored the rotating shaft system containing the crackes.
