摘要
Abstract
Mechanical fault diagnosis is a key factor in ensuring for the reliability and safety of modern automated mechanical systems that are becoming increasingly complex.As a core component of modern mechanical system,the health status of rolling bearings directly affects the performance and lifespan of the bearing-driven machinery,and has always been a popular topic in the field of fault diagnosis.Traditional bearing fault detection methods often rely on manual feature extraction and classifier design,and their efficiency and accuracy are limited.In this paper,we propose a deep learning method based on convolutional neural network(CNN)and long short-term memory network(LSTM):WDC-LSTM.CNNs extract key local features from vibration signals,while LSTMs process these feature sequences to capture continuity and dynamic changes over time,and the combination of the two enables the model to account for both the spatial and temporal characteristics of bearing failure data to achieve end-to-end bearing fault detection.To validate the performance of the method,we conducted experiments using the Case Western Reserve University bearing fault dataset and compared it to other common methods.The experimental results show that the bearing fault detection method based on CNN and LSTM(WDC-LSTM)has high accuracy and strong generalization ability in bearing fault classification.关键词
