【摘要】 传统的基于单通道信号的旋转机械不对中故障的诊断主要依靠幅值谱和相位谱特征,易出现误诊和漏诊情况,很难对不对中类型做出准确诊断,对于不对中方向的确定也是一大难点。针对以上问题,提出了基于全矢谱技术的不对中故障诊断方法,通过对互相垂直的两个通道信号的融合,不但能够提高对不对中特征提取的可靠性,而且能够给出不对中的具体方向,能够给维修人员提供更有针对性的指导意见,提高设备故障处理效率。本文研究结果对于提高旋转机械不对中故障的识别与诊断具有重要的指导意义和参考价值。更多还原

【Abstract】 Amplitude spectrum and phase spectrum are often used in the diagnosis of misalignment faults in traditional fault diagnostic technology based on single channel signal.Misdiagnosis and missed diagnosis often happens.And the direction of misalignment is hard to confirm by this means.Aimed at the problems,a new diagnosis method of misalignment faults based Full Vector Spectrum technology is presented.By fussing the signals from two perpendicular channels,the reliability of spectrum feather exactions is enhanced,and the direction of misalignment can be confirmed.It is in favor of diagnosis and treatment of misalignment faults.Furthermore,it can increase efficiency of treatment of plants.The research results are valuable to the identity and diagnosis of misalignment faults.更多还原
