EspañolSuburban railway 10 cm and main line railway 12 cm
The tests were carried out on FFU synthetic sleepers with dimensions 10 x 26 x 260 cm (suburban railway) and 12 x 26 x 260 cm (main line railway).
Testing included:
- Behaviour of the sleeper under vertical and horizontal loads in the vibration fatigue test. Support in the ballast bed on the basis of DIN EN 13481-3.
- Static and dynamic testing of synthetic sleepers based on DIN EN 13230-2.
- Extraction tests on sleeper screws according to DIN EN 13481-2.
Fatigue test sleeper centre
A fatigue test of 2 million load cycles was conducted in the centre of the sleeper based on DIN EN 13230-4.
The load applied was initially up to 65 kN. The fatigue test then ensued with a torque of 23 kNm.
This torque corresponds to an axle load of 250 kN and a train speed v ≥ 200 km/h.
No damage to the sleeper could be established during the fatigue test of 2 million load cycles.
Fatigue pressure test under the rail support
Was carried out on the basis of DIN EN 13230-2 (concrete sleepers).
A load of 150 kN was selected for the fatigue test. This corresponds to an axle load of 250 kN and a train speed v < 200 km/h.
A static load of 1.2 x 150 kN = 180 kN was applied before the fatigue test.
After the fatigue test the static load was increased to 2 x 150 kN = 300 kN.
Using grooved plate Rph 1 with the dimensions 160 mm x 345 mm the fatigue test was carried out under the rail support on two sleepers (height 120 mm).
A 5 mm thick intermediate plate of synthetic material was also installed under the grooved plate.
The first sleeper was subjected to 5 million load cycles and the second to 2 million load cycles.
