In this paper , the use of emd method in machine fault diagnosis is discussed , and two new fault diagnosis methods are introduced . 1 本文就emd方法在机械故障中的应用进行了探讨,提出了两种机械故障诊断的方法: 1
This subject was brought forward from practical application , so the combination with the single machine fault diagnosis is considered 本课题是针对实际工程项目提出的,因此也考虑了与原有单机监测系统的结合情况。
Machine fault diagnosis is a science of identifying the running state of device by studying the varying information of the device running state 机械故障诊断是研究设备运行状态信息的变化,进而识别设备运行状态的科学。
In this thesis , the rotating machine fault diagnosis system and the motor fault diagnosis system of the intelligent diagnosis system of mechanical equipment fault are validated by cases 本文通过实例运行对智能诊断系统中的旋转类故障诊断和电动机故障诊断两个子系统模块进行了验证。
Application of emd and correlative dimension to diagnosis machine fault fractal dimension can be used to show the structure character of the signal , and is widely used in denoting the nonlinear system 利用emd方法和关联维数进行机械故障诊断。分数维表征了信号的结构特征,广泛地被用于非线性系统行为的刻划中。
