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

The clamping force of an elastic rail clip, the toe load, is the parameter that keeps the rail held down and the fastening system working, and it does

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-

Rails generate significant longitudinal temperature forces under temperature changes, which are directly transmitted to fastening components such as s
