| 摘 要： | 为研究端面扭动摩擦特性,研制了端面扭动摩擦特性测量装置,进行了玻璃纤维增强铸型尼龙（MC尼龙）复合材料与45#钢在123 N法向载荷下的扭动与滑动摩擦学试验,扭动角位移幅值为60°和90°,使用扫描电镜观察MC尼龙复合材料磨损表面形貌,采用光学显微镜观察45#钢偶副表面转移膜形貌.结果表明：扭动摩擦的扭矩-角位移（T-θ）曲线随着循环次数的增加保持平行四边形,而摩擦扭矩随之升高;扭动状态下的摩擦系数高于滑动摩擦系数,扭动磨损后MC尼龙试样质量增加;滑动状态下的磨损机理主要为塑性变形和疲劳磨损,扭动状态下的磨损机理为更为严重的黏着磨损和疲劳磨损;滑动摩擦状态下,45#钢偶副表面形成了大面积连续的转移膜,扭动状态下,45#钢偶副表面只在接触中心区域有少量条块状转移物质.
