Special Issue Information

Dear Colleagues,

Fault diagnosis in machinery manufacturing is a critical aspect that ensures the reliability, safety, and efficiency of industrial operations. In the age of Industry 4.0, production equipment is becoming more integrated and intelligent, introducing new challenges for data-driven process monitoring and fault diagnosis. This journal explores the current technologies and methodologies used in diagnosing faults in machinery. It highlights the integration of traditional techniques, such as vibration analysis and thermal imaging, with modern advancements like machine learning, artificial intelligence (AI), and the Internet of Things (IoT). These innovations enable real-time monitoring, predictive maintenance, and data-driven decision-making. This journal also integrates the challenges in implementing fault diagnosis systems, including data management, integration with existing systems, and the need for skilled personnel.

Through recent R&D advancements, insights have been provided into the future trends in fault diagnosis technologies, emphasizing the potential for increased automation and accuracy, as well as the development of smarter manufacturing processes.

With the development of intelligent grid systems, smart circuit breakers are widely used. The control circuit is the core component of the smart circuit breaker, making its performance degradation characteristics highly significant. This paper focuses on the control circuit’s accelerated degradation test and performance degradation characteristics. First, an accelerated degradation test is designed, and a test platform is established. By analyzing the degradation mechanism of the intelligent circuit breaker control loop, the key weak links in the control loop are determined, and then the monitoring quantity is determined. Then, degradation data are preprocessed to extract features from the time, frequency, and wavelet domains. The multidimensional evaluation index model is applied to select the optimal features, fit the degradation trend, and use the fixed segmentation algorithm to divide the degradation stages and analyze the performance degradation characteristics of the control circuit. The experimental results show that the turning points of the two-stage degradation process at 85 °C, 95 °C, and 105 °C are 78.8%, 77.6%, and 77.0%, respectively. The position of the turning point is relatively fixed. The key circuit’s PSpice simulation model is built to verify the two-stage nonlinear characteristics observed in the experimental results. Finally, the results are verified by the Pearson correlation coefficient. The results show that the Pearson correlation coefficient between the simulation and accelerated life test results is above 0.9158, and the consistency between the two is high. Full article
