Deviations in the installation position, torque, and flatness of components such as spring clips, pressure plates, baffles, and pads can alter the tra

Heavy-haul trains have large axle weights and longitudinal forces. In addition to being subjected to tensile forces, track spikes also bear enormous s

Track gauge baffles are key components for adjusting and maintaining track gauge. Long-term exposure to rail pressure and friction will cause wear and

In humid and corrosive environments, track bolts corrode and expand, compressing the surrounding anchoring agent and sleepers, generating internal str

The strength, toughness, and elasticity of spring clips are primarily determined by the heat treatment process. Insufficient or excessive heat treatme

Rail corrugation wear significantly increases wheel-rail impact, causing a sharp increase in the dynamic load on fastening components such as spring c

Bolt threads are critical components for transmitting torque and preload. Damage to them can lead to fastening failure, loosening, and detachment, sev

Pressure plates in curved sections are subjected to continuous lateral compression and friction, resulting in a much higher wear rate than those in st

The pull-out strength of rail spikes is a core indicator for measuring anchorage effectiveness. Insufficient pull-out strength directly leads to later

Under long-term vibration, temperature changes, and fretting wear, the clamping pressure of spring clips gradually decreases. Understanding the attenu

The strength of the fishplate material directly determines the joint's load-bearing capacity. Insufficient strength can lead to deformation and cracki

Rail pads are key components for controlling track stiffness. Uneven stiffness directly causes unevenness in rail height and level, exacerbates wheel-
