전기 커넥터의 프레팅 마모 시 발생하는 마모 잔해로 인한 접점 성능 저하 문제를 해결하기 위해 전기 커넥터의 접점에 대한 저주파 프레팅 마모 실험을 수행하고, 마모 잔해의 축적 및 분포 전기 용량 단층 촬영 기술로 검출되었습니다. 프레팅 사이클, 진동 방향, 진동 주파수 및 진동 진폭이 마모 잔해의 축적 및 분포에 미치는 영향을 분석했습니다. 마모 잔해의 특성값과 접촉 저항 값 사이의 상관관계를 연구하고, 마모 잔해의 축적과 분포를 기반으로 한 성능 저하 모델을 구축했습니다. 결과는 프레팅 마모와 성능 저하가 축방향 진동에서 가장 심각한 것으로 나타났습니다. 마모 잔해의 특성값과 접촉 저항은 프레팅 주기, 진동 주파수 및 진동 진폭과 양의 상관 관계가 있습니다. 마모 잔해의 특성값의 합과 접촉 저항값 사이에는 강한 상관관계가 있습니다. 마모 잔해의 특성값으로 구성된 전기 커넥터의 프레팅 마모 성능 저하에 대한 ABC-SVR 모델의 예측 오류는 6% 미만입니다. 따라서 접촉 하위 영역의 마모 잔해의 특성 값은 프레팅 마모 정도와 성능 저하 과정을 정량적으로 설명할 수 있습니다.

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.
