Visant le problème de la détérioration des performances de contact causée par les débris d'usure générés lors de l'usure par contact du connecteur électrique, des expériences d'usure par contact à basse fréquence ont été réalisées sur les contacts des connecteurs électriques, l'accumulation et la répartition des débris d'usure. ont été détectés par la technologie de tomographie par capacité électrique ; l'influence des cycles de fretting, de la direction des vibrations, de la fréquence et de l'amplitude des vibrations sur l'accumulation et la répartition des débris d'usure a été analysée ; la corrélation entre la valeur caractéristique des débris d'usure et la valeur de la résistance de contact a été étudiée, et un modèle de dégradation des performances basé sur l'accumulation et la répartition des débris d'usure a été construit. Les résultats montrent que l'usure par frottement et la dégradation des performances sont les plus graves en matière de vibrations axiales ; la valeur caractéristique des débris d'usure et de la résistance de contact est positivement corrélée aux cycles de fretting, à la fréquence et à l'amplitude des vibrations ; il existe une forte corrélation entre la somme des valeurs caractéristiques des débris d'usure et la valeur de la résistance de contact ; l'erreur de prédiction du modèle ABC-SVR de dégradation des performances d'usure par frottement des connecteurs électriques construit par la valeur caractéristique des débris d'usure est inférieure à 6 %. Par conséquent, la valeur caractéristique des débris d’usure dans les sous-zones de contact peut décrire quantitativement le degré d’usure par frottement et le processus de dégradation des performances.

Abstract: Aiming at the problem of the deterioration of the contact performance caused by the wear debris generated during the fretting wear of the electrical connector, low-frequency fretting wear experiments were carried out on the contacts of electrical connectors, the accumulation and distribution of the wear debris were detected by the electrical capacitance tomography technology; the influence of fretting cycles, vibration direction, vibration frequency and vibration amplitude on the accumulation and distribution of wear debris were analyzed; the correlation between characteristic value of wear debris and contact resistance value was studied, and a performance degradation model based on the accumulation and distribution of wear debris was built. The results show that fretting wear and performance degradation are the most serious in axial vibration; the characteristic value of wear debris and contact resistance are positively correlated with the fretting cycles, vibration frequency and vibration amplitude; there is a strong correlation between the sum of characteristic value of wear debris and the contact resistance value; the prediction error of ABC-SVR model of fretting wear performance degradation of electrical connectors constructed by the characteristic value of wear debris is less than 6%. Therefore, the characteristic value of wear debris in contact subareas can quantitatively describe the degree of fretting wear and the process of performance degradation.
