Production Requirements for Track Elastic Fasteners

With the increase of the axle load of railway locomotives and the increase of train speed, as well as the development of urban rail transit and subway, spring bars, as a key link of track structure, are constantly developing, and their importance is becoming more and more important. countries are concerned.

On conventional lines, elastic strips with high buckle pressure and good elasticity are required to meet the needs of heavy-duty and high-speed lines; while in seamless lines of viaduct tracks, in order to reduce the interaction force between rails and bridges, fastener resistance is required Smaller, and ensure that the elastic strips have sufficient elasticity, that is, ensure that the elastic strips have a sufficiently low rigidity, so as to ensure that the buckle pressure loss caused by the compression of the under-rail cushion is small when the train passes, and the fasteners do not loosen.
