大型高速回转机械运行状态监测与故障诊断是保证设备长期安全运行的重要手段,是当前国内外工程领域应用研究的热点。西安交通大学机械监测与诊断研究室经过近10年来对石油化工行业大型高速回转机组运行状态的监测和分析,1988年提出了全息谱原理。它集成了大型回转机组在多个支承截面上两个相互垂直方向振动信号的幅、频、相信息,形成大型回转机械状态监测和故障诊断一整套综合分析的新理论,克服了传统诊断方法的片面性,并以全息谱原理为基
Large-scale high-speed rotary machinery operating condition monitoring and fault diagnosis is to ensure long-term safe operation of equipment is an important means of application of the current domestic and international engineering research hot spots. After nearly 10 years of monitoring and analyzing the operating status of large-scale high-speed rotary machines in the petrochemical industry, the principle of holographic spectroscopy was proposed in 1988. It integrates the information of amplitude, frequency and phase of two perpendicular vibration signals of a large slewing unit on multiple bearing sections to form a new comprehensive analysis of large-scale rotating machinery condition monitoring and fault diagnosis, which overcomes the traditional diagnostic methods One-sidedness and based on the holographic principle
