钢轨接头减振鱼尾板理论与试验分析

As the bolt tension increase, the tension of rail web, stress of joint bar and stress of joint bolt would increase accordingly, but the displacement of rail would become smaller.

螺栓扭矩增大，接头区钢轨轨腰拉力、夹板应力、螺杆内应力都会增大，而钢轨位移会随着螺栓扭矩的增大而减小。

The testing results about the use of new rail joint was introduced, which include the dynamic flexure stress of upper limb and lower margin of joint bar, shearing stress of horizontally neutral axis.

本文对三种新型钢轨接头现场使用情况的测试结果进行了介绍，主要包括测点处的钢轨接头夹板上、下缘动弯应力、夹板水平中性轴处剪应力。

The working principle, technical specifications and the application of rail vibration absorber joint plate, are described.

分析了钢轨接头病害及影响,阐述了钢轨减振接头夹板的工作原理和使用情况, 并介绍了其使用技术要求.

Higher train speed, heavier axle loads and greater traffic density result in more severe damage of track components at rail joint.

随着列车速度和轴重的提高和行车密度的加大，钢轨接头的损伤也随之加剧。
