What Are The Performance Characteristics of Rail Fastening?

Sep. 08, 2017

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

1.Rail Fastener should have sufficient strength and durability. Because of long running time, high traffic density, poor maintenance condition, rail fastening must have enough strength and durability to ensure traffic safety.

2.A certain gauge and level adjustment performance. 

3.Good insulation performance. Rail transit generally use track as a return rail, which requires the Railway Fastener must have good insulation performance to prevent leakage of current through the fastener, resulting in electrical corrosion of the structural reinforcement and municipal pipelines. 

4.Good damping elasticity. Urban rail transit, such as metro, goes through the residential areas. The environmental protection requirements of vibration reduction and noise reduction are very high. Rail fastenings must have good vibration damping performance, attenuate track vibration and reduce noise transmission.

5.There is a certain general interchangeability. Rail fastener structure should strive to simple, parts less, with a certain general interchangeability. Low cost, construction and maintenance is convenient.
