基于特征融合的机械核心部件剩余寿命预测
RUL Prediction of Mechanical Core Components Based on Feature Fusion
摘要
Abstract
Predictive maintenance of engineering machinery equipment can ensure the efficient operation of the equipment and the rational arrangement of maintenance plans,with the key lying in accurately predicting the RUL of equipment systems or core components.To address the challenges of feature extraction and prediction accuracy in predictive maintenance of engineering machinery equipment,we propose an Informer-based framework for the prediction of the RUL of core components of mechanical equipment based on feature fusion.Firstly,an optimized data utilization method is adopted to construct training samples according to the proportion of life.Bartlett high-pass filter and wavelet denoising are used to filter and denoise the raw data,and feature extension is performed to extract key features from the raw data.The XGBoost algorithm is used for feature selection.Then,the selected data is classified by equipment type,and an Informer-based predictive model for the RUL of mechanical core components is designed for classification training.The model is validated using public datasets,demonstrating that the Informer predictive model based on feature fusion achieves the highest prediction accuracy compared to other models.关键词
