摘要钢丝间的微动磨损以及由此引起的钢丝的疲劳断裂是提升钢丝绳失效的主要原因之一。 - Thirdly , under temperature stress the connectors " failure mechanism is oxide film thickening , while through analyzing the structure and dynamic character of electrical connectors , the failure mechanism of electrical connectors is fretting under vibration stress . combined these two stresses , their failure mechanism are fretting either , but the velocity of degeneration are accelerating , because temperature stress create more oxide production let connectors failure more easily . in a following part of dissertation we could make reliability model according to these analyzing
第三，分析了电连接器在温度应力下的失效机理；并通过对电连接器的结构及电连接器在振动应力作用下的动态特性进行分析，探讨了电连接器在振动应力作用下的失效机理；通过对电连接器进行环境温度、振动应力综合作用下的失效分析，确定其主要失效机理为微动磨损，结合微动图理论对微动过程进行分析，为电连接器的可靠性建模提供了依据。 - A series of tests were performed on the self - made fretting wear test rig to examine the fretting wear of steels , by taking the wear depth of steel wires as a characterization parameter describing the fretting wear in relation to contact load and fretting time . the results demonstrates that the fretting wear depth increases with the increasing of the contact load and fretting time
结果表明，钢丝试样的微动磨损深度随着接触载荷和微动时间的增加而呈增长趋势，但由于接触面积和接触应力在微动磨损过程中随着接触载荷和微动时间的变化而变化，使磨损深度在不同磨损工况下增长趋势不同。
