The cable structure has been widely adopted in some engineering applications. Cable clamp and its anti-slipping performance is the key factor to assure the bearing capacity for cable structure. This paper is concerned with the slipping resistance between cable clamp and Z shape full locked coil cables in a two-way orthogonal cable-net structure. Firstly, a new method for laboratory test of the clamp is designed, which is carried out under cable tension. The clamping force of high-strength bolt and the pushing force are monitored in real time. According to force reaction–displacement graphs obtained from the test, the reasonable anti-slipping ultimate frictional force of the clamp is determined and the precise friction coefficient of the clamp is calculated by the data from real-time monitoring. Finally, through the simulation analysis of nonlinear finite element model, the results are basically consistent with the laboratory test. The proposed method can be extended to solve anti-slipping problems of similar cable clamps.

双向正交全锁定线圈电缆夹钳防滑性能的数值和实验研究
电缆结构已在某些工程应用中被广泛采用。电缆夹及其防滑性能是确保电缆结构承载能力的关键因素。本文关注的是双向正交电缆网结构中电缆夹和Z形全锁定线圈电缆之间的滑动阻力。首先,设计了一种在电缆张力下进行夹具测试的新方法。实时监控高强度螺栓的夹紧力和推力。根据从测试中获得的力反作用力-位移图,可以确定夹具的合理防滑极限摩擦力,并通过实时监测数据计算出夹具的精确摩擦系数。最后,通过对非线性有限元模型的仿真分析,结果与实验室试验基本吻合。所提出的方法可以扩展为解决类似电缆夹的防滑问题。
