Research on the Mechanism and Dynamic Characteristics of Intermittent Failure of Electrical Connectors
Source abstract
Abstract
Aging or damaged electrical connectors always suffer intermittent failures (IFs) during operation. Because there are few quantitative studies on electrical connector intermittent failure mechanisms, the intermittent failures of electrical connectors are difficult to isolate. Therefore, the mechanism and dynamic characteristics of intermittent failure is studied in this paper. Firstly, the degradation process of an electrical connector is analyzed. Secondly, according to electrical contact model, the intermittent failure mechanism caused by vibration is studied. Thirdly, to make a profound study on dynamic behavior of intermittent failure, an intermittent failure dynamic model is proposed, and the behaviors of intermittent failure are analyzed. Finally, a simulation case is conducted to verify the correctness of the intermittent failure mechanism and the effectiveness of the intermittent failure dynamic model.
