摘要
根据空压机齿轮变速箱振动和噪声谱 ,应用振动、噪声信号的倒频分析技术给出了剔除反射回声方法 ,并综合分析了实测信号 ,为空压机齿轮变速箱故障分析提供了依据。
According to gear sifting's vibration and noise spectrum,using inverted frequency spectrum analysis technology of vibration noise signal to have the method of rejecting echo and synthetic analyzed actual measured signal,provided the base for gear shifting box fault of air press.
