| 摘 要： | 利用相对小波能量作为特征进行滚动轴承故障诊断.首先将滚动轴承振动信号进行离散小波分解,然后利用各频带的相对小波能量作为特征向量,使用支持向量机作为分类器对轴承故障进行分类.针对轴承内圈故障、滚动体故障、外圈故障3种故障及不同损伤程度的实测数据进行多种分类实验,实验结果表明利用相对小波能量作为滚动轴承故障诊断的特征非常有...

| Abstract: | The relative wavelet energy technique is introduced to roller bearing fault diagnosis in this paper.The original bearing vibration signal is decomposed by discrete wavelet transform.Then the relative wavelet energy is served as feature vector.In the classification,the support vector machine method is used to identify the different faults.Experiments were conducted on roller bearing with three different fault categories and several levels of fault severity.The experimental results indicate that the proposed ... |
