Product Introduction

FST type high damping fastener is a new type of track damping fastener. By adopting a supporting design, this kind of damping fastener can clamp and lift the rail through an elastic rubber wedge to significantly reduce the transmiss of noise caused by wheel-rail vibration to the foundation, reduce rail vibration, reduce noise radiation and improve the ride comfortness. The fastening system is especially suitable for areas where buildings around the subway line are very sensitive to vibration and areas where the line needs vibration reduction, reconstruction and upgrading.

Key Parameters

(1) Static stiffness: 5-10 kN/mm;

(2) Compared with that of the ordinary elastic split fastener, the damping test value is more than 10dB;

(3) After 3million fatigue tests, the change rate of static stiffness is not more than 10%, and the change rate of longitudinal resistance is not more than 10%. All parts and components are not damaged.
