摘要
扭矩系数对于螺栓联接拧紧力矩以及轴向力的确定起着至关重要的作用,以叶根螺栓联接组件作为试验模型,通过应变电测试验方法测量螺栓拧紧力矩、杆部轴向力,以此得出螺栓扭矩系数。同时,文章采用的试验方法亦可测量螺栓杆部所受扭矩,通过理论公式换算可间接测试螺栓螺纹副以及螺帽头接触端面的摩擦系数。
Torque coefficient is necessary to determine the screw torque and axial force of the bolt-join. In this paper, an experimental model of blade-bolt-join is selected, and the torque coefficient of the bolt-join is obtained from the screw torque and axial forces which are measured based on the method of strain gauge measurement. At the same time, the torque of rod section is measured and the friction coefficient of the interface of screw thread and screw cap can also be tested by this method.
