摘 要: This paper proposes a novel method based on hyper-ellipsoidal Support Vector Data Description (SVDD) for bearing fault diagnosis. First, features of bearing fault data are selected based on integrated indicators to solve the overlapping problems of features from different bearing faults. Second, considering that multiple fault data of bearings in practical applications cannot be obtained at one time in a short time, the incremental learning model is established by creating high-dimensional spatial feature hyper-ellipsoids with the concept of SVDD. Finally, we conducted experiments by two laboratory data sets to validate the effectiveness of the proposed method.

本文提出了一种基于超椭球形支持向量数据描述(SVDD)的新型轴承故障诊断方法。首先,通过综合指标选择轴承故障数据的特征,以解决不同故障类型特征之间重叠的问题。其次,考虑到实际应用中无法在短时间内一次性获取多个轴承的故障数据,本文采用SVDD的思想构建高维空间特征超椭球体,从而建立增量学习模型。最后,通过两个实验室数据集进行实验,验证了该方法的有效性。
