摘要

为减轻故障图标特征偏移和数据值缺失导致的特征缺失对轴承故障诊断的影响,本文提出了一种基于空间频率滤波器和多尺度特征重组校准网络(MSRCN)的故障诊断方法。首先,将故障特征转换为频带特征,并利用 Mel 滤波器实现特征增强,以削弱故障特征偏移的影响。然后,利用 MSRCN 中的空间校准模块(SC)进一步改善故障特征分布,消除故障特征偏移问题。接下来,为了解决故障特征缺失问题,利用 MSRCN 对剩余的故障特征进行多尺度重组采样,得到新的故障特征,从而克服了故障特征缺失对故障诊断的影响。最后,在 CWRU 和 XJTU-SY 滚动轴承数据集上进行了实验,验证了该算法能有效解决故障特征偏移和缺失问题。同时,实验结果证明本文提出的算法可以实现高精度故障诊断。

Bearing fault diagnosis based on data missing and feature shift suppression strategy
To mitigate the impact of fault iconic feature shift and feature missing due to missing data values on bearing fault diagnosis, this paper proposes a fault diagnosis method based on a spatial frequency filter and a Multi-Scale feature recombination calibration network (MSRCN). First, the fault features are converted into frequency band features and feature enhancement is realized using Mel filters to weaken the effect of fault feature offset. Then, the spatial calibration module (SC) in the MSRCN is utilized to further improve the fault feature distribution and eliminate the fault feature offset problem. Next, to solve the fault feature missing problem, the remaining fault features are sampled by multi-scale reorganization using MSRCN to obtain new fault features, which overcomes the effect of fault feature missing on fault diagnosis. Finally, experiments are conducted on CWRU and XJTU-SY rolling bearing datasets to verify that the algorithm can effectively solve the fault feature offset and missing problem. Meanwhile, the experimental results prove that the algorithm proposed in this paper can realize high-precision fault diagnosis.

期刊介绍: Systems and control studies provide a unifying framework for a wide range of engineering disciplines and industrial applications. The Journal of Systems and Control Engineering refleSystems and control studies provide a unifying framework for a wide range of engineering disciplines and industrial applications. The Journal of Systems and Control Engineering reflects this diversity by giving prominence to experimental application and industrial studies. "It is clear from the feedback we receive that the Journal is now recognised as one of the leaders in its field. We are particularly interested in highlighting experimental applications and industrial studies, but also new theoretical developments which are likely to provide the foundation for future applications. In 2009, we launched a new Series of "Forward Look" papers written by leading researchers and practitioners. These short articles are intended to be provocative and help to set the agenda for future developments. We continue to strive for fast decision times and minimum delays in the production processes." Professor Cliff Burrows - University of Bath, UK This journal is a member of the Committee on Publication Ethics (COPE).cts this diversity by giving prominence to experimental application and industrial studies.
