摘　　要：以旋转机械为研究对象,采用Matlab软件平台,通过绘制转子在不平衡、摩擦典型故障时的轴心轨迹图方法,监测和分析旋转机械的振动故障。采用平均法提纯了轴心轨迹图,减小了随机噪声的影响,还原出干净的轴心轨迹图。试验表明,采用Matlab方法不会造成数据量的减少及细节信号的丢失,能较好地诊断转子的振动故障。Taking rotating machinery as research objects,the vibration faults are monitored and analyzed by using Matlab software platform to draw the axis orbit chart of the rotor in the imbalance and friction failure.The axis orbit chart is purified and restored by the method of average to reduce the influence of random noise.Experiments show that the method is simple,not causing the data amount reducing and the signal details losing,better diagnosing the vibration of the rotor faults.
