Rail fastening system drawing design
Determine design requirements
Track type: high speed railway, heavy haul railway, subway, light rail, etc.
Load requirements: axle load, speed, traffic density.
Environmental conditions: temperature change, humidity, corrosive environment.
Standard specifications: comply with international standards (such as EN standards, AREMA standards) or customer specific requirements.
Determine the type of fastener system
According to the track type and load requirements, select the appropriate fastener system type, elastic fastener system, rigid fastener system, direct fixing system.
Draw the overall layout
Track cross section: Shows the relative positions of rails, fasteners, sleepers (or track plates).
Plan: Shows the distribution and spacing of fasteners on the track.
Side view: Shows how the fastener is connected to the sleeper.
Design fastener assembly
Rail Pad: Design size, material (such as rubber or polyurethane) and thickness.
Clip: Design shape, material and elastic properties.
Bolts and nuts: Determine size, material and fastening force.
Insulation components: Design insulation gaskets or bushings to prevent current leakage.
Anti-loosening device: Design anti-loosening washer or locking device to ensure that the fastener is not loose in the vibration environment.
Material selection
Steel: Used for elastic bars, bolts and gusset plates.
Rubber or elastic material: used for shock absorption and insulation.
Anticorrosive coatings, such as galvanized or epoxy coatings, are used to improve durability.
Dimensioning and tolerances
All key dimensions must be clearly marked, including length, width, thickness and aperture.
Note tolerances to ensure component interchangeability and installation accuracy.
