摘　　要：对螺纹连接副结构防松机理进行了螺纹受力、螺纹自锁条件和支承面受力分析,阐述了造成螺纹连接副松动的主要原因。选取接触网紧固件M10和M12连接螺栓测试样品,针对不同防松方式进行了静动态测试,分析总结出不同防松方式技术差异特性,提出了接触网不同紧固件防松方式建议,对接触网工程建设有一定的参考价值。The paper analyzes the anti-loosening mechanism of thread connecting sets in terms of thread stress, self-locking conditions of thread and stress of supporting face, illustrates main factors resulting in loosening of thread connecting sets. Bolts of M10 and M12, served as OCS fasteners, are selected as samples for testing, both static and dynamic tests are made under different anti-loosening modes, analyzes and summarizes the technological differences under different anti-loosening modes, and puts forward the proposals for adopting the anti-loosening modes for OCS, providing certain references for construction of OCS engineering.
