Research on fault diagnosis of rolling bearing based on ALIF and TMFDE

摘要: 为了提高滚动轴承的故障识别精度,提出了一种基于自适应局部迭代滤波(ALIF)和时移多尺度波动散布熵(TMFDE)的故障诊断方法。首先,利用ALIF对滚动轴承振动信号进行分解,获得一组IMF分量。其次,为了获得更集成的IMF分量,基于能量法评估各IMF分量的重要性,将前3阶分量视为有效分量。接着,利用TMFDE量化有效分量中的特征信息,构建故障特征向量。最后,将故障特征输入至粒子群优化的极限学习机中进行故障识别。利用东南大学的滚动轴承数据对该方法进行了评估,结果表明该方法能够准确地识别故障的类型,与其他方法相比,该方法在数据量较少时仍然具有优异的稳定性。

Abstract: In order to improve the fault identification accuracy of rolling bearing, a fault diagnosis method based on adaptive local iterative filtering (ALIF) and time-shifted multi-scale fluctuation dispersion entropy(TMFDE) was proposed. Firstly, the vibration signal of rolling bearing was decomposed by ALIF to obtain a set of IMF components. Secondly, to obtain more integrated IMF components, the importance of each IMF component was evaluated based on the energy method, and the first three components were regarded as effective components. Then, the TMFDE was used to quantify the feature information in the effective component and construct the fault feature vector. Finally, the fault features were input into the extreme learning machine optimized by particle swarm optimization for fault identification. The method was tested by using the rolling bearing data of Southeast University. The results show that the method can accurately identify the type of fault, and compared with other methods, this method still has excellent stability when the amount of data is small. -
