First, this paper proposes a novel frequency demodulation algorithm, where signals are first processed by autocorrelation analysis to eliminate random noise, and then implemented envelope demodulation to extract original modulation frequencies.
首先针对齿轮裂纹等局部故障的早期诊断,提出了一种时延自相关解调频方法。 该方法先对信号进行自相关预处理,然后再对信号的时延自相关函数进行包络解调,可以得原信号的调制频率。
