通过在实车上模拟坦克变速箱工作档位齿轮故障,利用Hilbert变换幅值解调法提取箱

体振动信号的包络,并对包络信号进行抽取和低频段频谱细化,提出了一种基于包络细化谱分析的

坦克变速箱工作档位齿轮故障诊断方法。

- A fault diagnosis method of working position gear in tank gear-box was put forward based on

simulating the fault of working position gear in actual tank gear-box, extracting the envelope of vibra-

tion signal by Hilbert transformation amplitude demodulation, and zooming low frequency band to the

envelope signal.
