In this paper, the longitudinal resistance and displacement of the WJ-8 conventional resistance fastener under vertical and torque loadings were experimentally conducted and the relationship between longitudinal resistance and displacement was established. To validate the experimental results, numerical simulation using a finite-element model of the fastener was established to obtain the longitudinal resistance variation of the conventional-resistance. Results of the analysis show that both results of the experiment and simulation are in agreements. Furthermore, the skid resistance frictional coefficient of the fastener system under the vertical load was studied and its variation rule under both vertical and torque loads was obtained. The longitudinal sliding resistance of fasteners under different torques and/or vertical loads followed a linear trend. Under load and no-load conditions, the skid-resistance frictional coefficient of the fastener system varied significantly.

本文对WJ-8常规阻力紧固件在垂直和扭矩载荷下的纵向阻力和位移进行了实验，建立了纵向阻力与位移之间的关系。为了验证实验结果，建立了使用有限元模型的紧固件的数值模拟，以获得常规电阻的纵向电阻变化。分析结果表明，实验结果与仿真结果均吻合。此外，研究了紧固件系统在垂直载荷下的防滑阻力摩擦系数，并得出了其在垂直载荷和扭矩载荷下的变化规律。紧固件在不同扭矩和/或垂直载荷下的纵向滑动阻力呈线性趋势。在有载和无载条件下，扣件系统的防滑摩擦系数都发生了显着变化。
