Elastic fastener system
As an important railway track connection element, elastic fastener system plays a vital role in railway construction and maintenance.
The elastic fastener system, also known as the railway shrapnel fastener system, is a part of the railway track used to connect the rail and the sleeper (or other types of rail under the foundation), also known as the intermediate connection part. Its main function is to fix the rail to the rail sleeper, maintain the gauge, and prevent the rail from moving horizontally and horizontally relative to the sleeper.

System type
Depending on the structure and function, elastic fastening systems can be divided into many types
Shrapnel fastening system
The system uses the elastic deformation of the shrapnel to realize the tight connection between the rail and the sleeper. The shrapnel fastener system has good vibration and noise reduction performance, which is suitable for high-speed railway and urban rail transit and other occasions requiring low noise and high stability.
Spring bar fastening system
The system provides the connection between the rail and the sleeper by bending the elastic bar. The spring bar fastening system is simple in structure and easy to install, and is widely used in various railway lines.
Main function
Shock-proof
The elastic fasteners system can effectively absorb the vibration and impact of the train, reduce the vibration and deformation of the track structure, and improve the running stability and ride comfort of the train.
Damping energy absorption
The elastic fasteners system has good vibration damping performance, can disperse and absorb the energy generated during train operation, reduce the stress level of the track structure, and extend the service life of the track structure.
Buffering force
When the train passes through, the elastic fastener system can cushion the impact of the train on the track structure and protect the track structure from damage.
