Rail corrugated wear can induce vibrations at specific frequencies. When the vibration frequency approaches the natural frequency of the elastic clip,

When fasteners are exposed to humid and waterlogged environments for extended periods, they will experience both general corrosion and electrochemical

The sleeper shoulder is a key structure that provides lateral support for the gauge block and elastic clips. Damage, chipping, and cracking of the sho

Fatigue cracks in spring rails mostly occur at stress concentration points, and their initiation and propagation follow typical patterns. Understandin

The hardness of gauge blocks (gauge baffles) directly affects their wear resistance, pressure resistance, and deformation resistance. Inconsistent har

Rails expand, contract, and warp under temperature changes, subjecting the elastic clip to continuous additional stress. This results in decreased fas

Under repeated rolling by trains, rail ends are prone to end crushing, edge thickening, and head collapse. This increases the joint step and intensifi

The embedded sleeve is a key connecting component between the bolts and the sleeper. Damage to it can lead to loosening, tilting, and insufficient pul

On small-radius curves, the wheel-rail lateral forces are enormous, and the elastic clips are often under eccentric compression, making them prone to
