摘　　要：转子轴心轨迹是判断机械转子运行状态和故障征兆的重要依据,文中研究了几种机械转子典型故障及其对应的频率和轴心轨迹特征,运用LabVIEW软件平台,开发出智能控件化虚拟式轴心轨迹测试分析系统,调用由VC++编写的动态链接库(DLL)函数实现对机械转子振动信号的采集.试验表明,转子轴心轨迹测试分析系统可实时显示轴心轨迹、轴心位置和两路相互垂直振动信号的波形和频谱,以此可以判断一些常见的旋转机械故障,计算出用来消除转子不平衡的平衡质量块的大小及坐标点位置.Rotor axis rotor. Detailed rotor their frequencies locus is an important basis for estimating the running states and faults of mechanical faults were analyzed and several typical faults and corresponding characteristics of orbits of shaft center line were studied. An axis locus analyzing system based on intelligent virtual control was developed, and the signal acquisition and analysis were realized by using LabVIEW7.0 and transferring the dynamic link library （DLL） function in VC ^＋＋ The results indicate that axis locus, axis location and the wave and spectrum of two orthogonal vibration signals can be real-time displayed, and some common faults of rotating machinery can be diagnosed by using the measurement system.
