Performance characteristics of rail fastener
Jan 31, 2018

According to the requirements of rail transit, the new rail fasteners should have the following characteristics:

1) adequate strength and durability.

The rail transit operation time is long, the driving density is high, the maintenance condition is poor, and the rail fasteners must have enough strength and durability to ensure the safety of driving.

2) have certain gauge and horizontal adjustment performance.

The rail transit USES the overall structure of the bed, the radius of the line curve is small, and the steel rail is worn.

This requires that the fasteners should have a certain gauge and horizontal adjustment performance, so as to solve the uneven settlement and construction error caused by the uneven settlement and construction error of the curved rail rail and the construction error, and the level of the rail is beyond the limit.

3) good insulation performance.

Rail transit are commonly used line tracks as reflux rail, which requires the fasteners must have good insulation property, prevent current leakage through the fasteners, cause structural steel and municipal pipeline corrosion.

4) there is a good elasticity of vibration reduction.

Subway and other urban rail transit travel through the residential area, and the environmental protection requirements for vibration and noise reduction are very high. The rail fastener must have good vibration damping performance, attenuation track vibration and reduce noise transmission.

5) there is a certain universal interchangeability.

The fastener structure should be simple, the parts are few, have certain universal interchangeability, the cost is low, construction and maintenance is convenient.
