Advances in Mechanical Engineering, Journal Year: 2025, Volume and Issue: 17(2)

Published: Feb. 1, 2025

Mechanical seals are critical components in the mechanical industry, and their operational status directly impacts performance of pumps, compressors, other machinery. Therefore, conducting research on fault diagnosis is essential. To enhance accuracy assessment model, we propose an integrated approach that leverages fusion multiple graph neural networks (GNNs). Firstly, recognizing diversity among different sensors, utilize multi-channel data to comprehensively represent state seal. These channels include various types sensors such as acoustic emission force sensors. Secondly, employ methods transform original into data, thereby continuously increasing datasets used for training. Finally, after training GNNs, output these through obtain evaluation results. The effectiveness our demonstrated using seal test data.

Batteries, Journal Year: 2025, Volume and Issue: 11(3), P. 85 - 85

Published: Feb. 20, 2025

Accurate estimation of the capacity lithium-ion batteries is crucial for battery management and secondary utilization, which can ensure healthy efficient operation system. In this paper, we propose multiple machine learning algorithms to estimate using incremental (IC) curve features, including adaptive moment (Adam) model, root mean square propagation (RMSprop) support vector regression (SVR) model. The Kalman filter algorithm first used construct IC curve, peak corresponding voltages correlated with life were analyzed extracted as features. three models then learn relationship between aging features capacity. Finally, cycle data validate performance proposed models. results show that Adam model performs better than other two models, balancing efficiency accuracy in throughout entire lifecycle.

Robust Clustering and Anomaly Detection of User Electricity Consumption Behavior Based on Correntropy

IET Generation Transmission & Distribution, Journal Year: 2025, Volume and Issue: 19(1)

Published: Jan. 1, 2025

ABSTRACT Anomaly detection in power systems is crucial for ensuring the safety and stability of electrical grids. Traditional methods struggle to extract meaningful features from electricity consumption data due significant differences usage patterns across various user types, such as residential industrial users. Applying a single model all categories increases feature complexity computational demands. Additionally, non‐Gaussian outliers caused by equipment measurement noise can significantly deviate normal patterns, making them difficult filter using standard methods. To address these challenges, this paper proposes robust, user‐type‐specific anomaly method. After preprocessing, correntropy‐based K‐means clustering method used separate users with noisy data. A two‐stage framework combining fuzzy logic convolutional neural network (CNN)‐long short‐term memory (LSTM) enhances both efficiency accuracy. The experiments were conducted open‐source datasets, results demonstrated that our achieved an accuracy 95%, which approximately 4% higher than traditional Isolation Forest This indicates approach effectively balances detection, its generalizability further validated on additional dataset.
