Small knowledge of railway fittings, the role and importance of bullet strips

The rail is fixed on the track bed or sleeper by elastic fasteners.The buckling part of the elastic fastener is mainly a bullet strip, which generates buckling pressure on the track through the bending and twisting deformation of the bullet strip, effectively ensuring the reliable connection between the rails, making the track as holistic as possible, preventing the rails from moving relative to the rails. The longitudinal and lateral movement of the sleepers ensures the normal gauge, thereby ensuring the safety of rail vehicles. In addition, due to the rigidity of train wheels and rails, vibration is inevitable, and the special elastic structure of the elastic strip makes it also have the role of absorbing the impact energy generated when the vehicle passes, so as to achieve shock absorption.
