 Vibration and Noise Hazards

 

Advantage

As a green transportation, rail transit has the characteristics of punctuality, speed, large-scale operation, energy saving and environmental protection, but because of vibration and noise, planning, construction and operation are restricted. Seriously affects the work and rest and health of residents, affects the safety and life of buildings, and affects operational safety, increasing operating costs. In order to break the current situation, we have developed and designed new products according to the characteristics of the existing fasteners, and optimized the performance of the fasteners. The harmonic fastener is composed of 10 parts including locking wedge, rail waist damping block, rail bottom damping block, lateral support, insulating sleeve and so on. A vertical elasticity is provided by the rail bottom damping block, which strengthens the vertical elasticity, and the rail waist damping block on the side makes the lateral stability strong. The piece also has the characteristics of preventing pulling up and suppressing wave grinding. It greatly reduces noise and vibration, making it possible to replace products on the market today, making rail transit greener. 

 

Production Process

 

Maintenance of Harmonic Fastener System

The Harmonic Fastener System is designed for long life and can be maintained for many years under normal operating conditions.      
The system consists of individual parts that can be dismantled with mounting clamps if required, all parts are replaceable.    
 
Harmonic fasteners include wear parts, such as rubber bumpers, that can be removed and inspected after years of use, and replaced if worn out.


 

Application

1. Curved sections prone to corrugation, especially small-radius curved sections;

2. Other fasteners use the transformation projects with excessive vibration;

3. The elevated track line can significantly reduce bridge vibration and secondary noise, and is more cost-effective than other measures;

4. Underground line sections with high vibration reduction requirements and excessive ground vibration;

5. The transformation of existing wire fasteners can improve the vibration reduction effect or delay the development of corrugation.
