摘要
转子轴心轨迹和轴心位置的变化是判断转子运行状态和故障征兆的重要依据。根据秦氏模型的原理,研究了智能控件化虚拟仪器的原理和形成过程,将智能控件化虚拟仪器这一全新的仪器概念引入到轴心轨迹分析系统中,在VMIDS系统上开发出智能控件化虚拟式轴心轨迹分析仪,可实时显示轴心轨迹和轴心位置,还可以显示两路相互垂直振动信号的波形和频谱。利用快速傅立叶变换(FFT)实现了轴心轨迹的分量分解和分量合成,能清楚地得到转子轴心轨迹的组成成分,判断一些常见的旋转机械故障。
The variation of rotor’s axis locus and its axis location is the essential evidence to determine the rotor’s running state and fault sign. According to the Qin’s Model principle, this paper studies on the principle of Intelligent Virtual Control, the principle and the forming process of Virtual Instrument based on Intelligent Virtual Control. An intelligent Control-oriented virtual axis analyzer is developed on the VMIDS system by introducing the new instrument concept—Virtual Instrument based on intelligent virtual controls to axis locus analyzing system. It can display axis locus and axis location real-time, and can display the wave and spectrums of two orthogonal vibration signals. Using fast fourier transform(FFT), it realizes components decomposition and components synthesis and display the component of axis locus clearly, so it can diagnoses some common fault of rotating machinery.
