Splet01. maj 2024 · The vibration velocities at the crib ballast (sleeper center-V2, rail-seat-V3 and sleeper edge-V6) were always higher than those at the shoulder ballast (surface-V7 and slope-V8), because the vibration caused by the quasi-static axle load excitation and the dynamic excitation of the wheel-rail contact underwent a significant decline during ... SpletThis paper presents a series of ballast box tests to investigate the ballast particle movement pattern inside railway ballast under different ballast, loading, moisture and shoulder confinement conditions. Eight wireless devices, SmartRocks, were embedded in different locations in the ballast box to monitor individual ballast particle movements.
Splet18. jun. 2024 · In general, the ballast track bed shoulder width in noncontinuous welded rail tracks is 200–300 mm and in continuous welded rail tracks is 400–450 mm. In the discrete-element model, we use ballast bed shoulder widths of 200, 400, and 600 mm to study the effect of shoulder width on the lateral and longitudinal resistance of the ballast bed. This shoulder should be at least 150 mm (6 inches) wide, and may be as wide as 450 mm (18 inches), [9] Ballast must be irregularly shaped to work properly Stones must be irregular, with sharp edges to ensure they properly interlock with each other and the ties to fully secure them against movement.
