摘　　要：为了确保航空用聚四氟乙烯/聚酰亚胺(PTFE/PI)绕包线在不同的环境和温度使用条件下受到摩擦作用后的有效性,对刮磨试验的不同实验条件进行研究,结合“粘着-犁沟”摩擦理论分析其刮磨失效的机理,探究不同的温度、负载和刮针直径对电线电缆刮磨失效次数的影响,为研制单位开展电线电缆耐刮磨试验提供指导,助力电线电缆的质量和可靠性提升。In order to ensure the effectiveness of aerospace PTFE/PI wrapped wire under different environmental and temperature conditions after being subjected to friction,the research is carried out under different experimental conditions of scratch grinding test.Combined with the“adhesion-furrow friction theory”,the mechanism of its scraping failure is analyzed,and the effects of different temperatures,different loads,and different scrapping needle diameters on the number of scraping failures of wires and cables are explored,which provides guidance for the development unit to carry out the scraping test of wire and cable,and helps to improve the quality and reliability of wire and cable.
