摘要
阶比谱分析是机械设备故障的重要诊断方法。为实现对旋转机械待诊断信号进行阶比谱分析,本文提出了一种运用常规通道切换式数据采集装置。根据转轴角速度波动来获取待诊断信号的整周期、等角度采样数据亦即阶比数据的新方法。仿真实验结果证明,这种方法是正确、可用的。
The analysis method of fixed-angle spectrum (FAS) is an importantmethod in the filed of diagnosis about mechanical equipment. For realizingFAS about pre-diagnosis signal of rotating machinery, in this paper, a newmethod to catch whole periods and fixed-angles samples of pre-diagnosticsignal has been proposed, which accounted the wave of angular velocity ofrotating axle and used channel turnning data acquisition system. The resultsof simulation has shown this method is correct and usable.
