As the core connector of a rail joint, the fishplate's mechanical properties must match the rail strength and track load. The joint design must balanc

Elastic rail clips fail through fatigue, not through a single overload. Every train pass bends the clip, and over millions of cycles stress concentrat

The stiffness parameters of the track pad directly affect the overall stiffness distribution of the track. They need to be precisely matched according

Bolt loosening is driven by transverse vibration, embedment of surface asperities, creep at temperature and gasket relaxation, and each mechanism call

Rail welding is the core process of track laying. Its welding process, joint strength, and toughness indicators must meet the requirements of line ope

As an important component of the rail fastening system, the structural form, strength index, and installation method of rail plates must be compatible

The strength, corrosion resistance, and dimensional accuracy of rail spikes must meet installation requirements, and their type selection is closely r

The materials, dimensions, and performance of the fishplate and bolts must be compatible. The reliability of the track connection is ensured through s

The clipping force, fatigue life, and material properties are the core performance indicators. The compatibility type should be selected according to

Rail pads are classified into types such as natural rubber and synthetic rubber according to their materials. Their hardness, vibration damping, and a

Track fastening systems are divided into different performance levels according to axle load and curve radius. Their longitudinal resistance, vertical

There are significant differences between national standard and foreign standard rails in terms of material, size, and performance requirements. The s
