摘要
以旋转机械振动参数图形为研究对象,指出了基于图形识别技术的旋转机械故障诊断方法存在的局限性。利用旋转机械具有周期激振的特点,研究了基于转子动力学理论的旋转机械参数图形插值重构方法。利用转子动力学理论构造振动响应基函数对实验测取的旋转机械参数图形进行插值重构。通过对插值后的图形进行诊断可有效地提高诊断准确率,进而验证了所提方法的有效性,为准确诊断设备故障打下良好基础。
Taking the rotating machinery parameters image as the object of study,this paper presented the existence drawback of fault diagnosis method based on image recognition for rotating machinery.According to the characteristic of the rotating machinery periodic excited,the method of applying rotor dynamics theory to construct the basic function of the vibration response so as to deal with graph by means of interpolation-reconstruction treatment was studied.The diagnosis accuracy is effectively improved by diagnosing the interpolating image,which validates the presented method is effective.This supplies a better basis for accurate diagnostic machinery fault.
