Rail gauge tie rod is an important accessory of railway line. Its principle is to use a rod to connect two steel rails to improve the lateral stability of the railway rail and the ability of the track to maintain the gauge. Some lines have track circuits, and the rail gauge rods are separated by insulating parts. If the rail gauge tie rod is missing, it will lead to an error in the gauge. When the train travels to this section, it will cause the train to derail, and even if it is serious, it may cause the train to subvert, with disastrous consequences.
The railway turnout structure is very complex, short-lived and unsafe to drive, and it is also very laborious in maintenance and maintenance. It is one of the three weak links in the track structure. Frequent maintenance or replacement of railway turnouts will seriously affect the normal operation of heavy-duty railways. Based on the rigid-flexible coupling method, a refined vehicle is established as a model for the dynamic analysis of railway turnouts, combined with the test results to check the reliability of the model, and the data obtained from the model are used to analyze and study the way of crossing the turnout, the traveling speed and the dynamic characteristics of the train turnout system The impact of the law, and also evaluated the feasibility of the site.
When 20 sets of rail guage rods are installed on the side strands of the steel rail, the lateral force of the wheel and rail can be reduced by 43.0%, and the vertical force of the wheel and rail can be reduced by 5.1%. The more rail gauge tie rods, the lower the indicators. According to various index factors, it is recommended to set 10-14 sets of rail gauge tie rods on the side bone line of the fork zone. It is recommended to use a rail bottom slope of 1:20 to reduce the wheel-rail force, so that the effect is more significant. Among them, the wheel-rail lateral force can be reduced by 14.8%, and the wheel-rail vertical force can be reduced by 16.7%. When the section width increases by 2mm, the wheel-rail force and contact stress increase can reach 8.3%, and the east bending stress of the steel rail of the corresponding section decreases by 18.8%. Therefore, it is recommended to thicken 2mm to optimize the load-bearing section of the core rail and the tip rail.
