| 1 | A Deep Learning Approach for Fault Diagnosis of Induction Motors in Manufacturing显示文摘Extracting features from original signals is a key procedure for traditional fault diagnosis of induction motors, as it directly influences the performance of fault recognition. However, high quality features need expert knowledge and human intervention. In this paper,a deep learning approach based on deep belief networks(DBN) is developed to learn features from frequency distribution of vibration signals with the purpose of characterizing working status of induction motors. It combines feature extraction procedure with classification task together to achieve automated and intelligent fault diagnosis. The DBN model is built by stacking multiple-units of restricted Boltzmann machine(RBM), and is trained using layer-bylayer pre-training algorithm. Compared with traditional diagnostic approaches where feature extraction is needed,the presented approach has the ability of learning hierarchical representations, which are suitable for fault classification, directly from frequency distribution of the measurement data. The structure of the DBN model is investigated as the scale and depth of the DBN architecture directly affect its classification performance. Experimental study conducted on a machine fault simulator verifies the effectiveness of the deep learning approach for fault diagnosis of induction motors. This research proposes an intelligent diagnosis method for induction motor which utilizes deep learning model to automatically learn features from sensor data and realize working status recognition. | Si-Yu Shao Wen-Jun Sun Ru-Qiang Yan Peng Wang Robert X Gao | 2017 | Chinese Journal of Mechanical Engineering2017，30，6： | 17 |
| 2 | 包络变形对阶比分析结果的影响及消除方法显示文摘转速变化的滚动轴承故障诊断通常先采用计算阶比跟踪技术消除变转速的影响,再进行阶比分析获得故障特征。然而,等角度重采样会引起冲击包络变形进而导致阶比分析结果产生偏差,在转速变化范围较大时这个偏差必须要受到重视。介绍了等角度重采样方法,仿真了包络变形对阶比分析结果的影响,给出了峰值点间隔变化量详细的理论推导,提出了通过修正角度变换值来消除包络变形影响的方法,并进行了实验验证。研究结果显示,包络在宽窄方向的变形对阶比分析结果没有影响;相邻包络峰值点间隔的变化对阶比分析结果产生影响;在角度序列逐点减去峰值点间隔变化量可消除包络变形对阶比分析结果的影响。 | 程卫东 王天杨 Wang Jin-jiang Robert X Gao 温伟刚 李建勇 | 2015 | 振动工程学报2015，28，3： | 6 |
