Design, Supply, Installation, Commissioning and Maintenance of Railway Testing Systems
The high speed rail Infrastructure Testing Facility (ITF) is an outdoor structure for the testing of railway track components and earth embankments.
The testing rig will incorporate hydraulic actuators located on a reaction beam, to apply downward dynamic vertical loads onto stationary embankment structures.
The reaction beam will be 10 m long and its vertical position changeable between heights of 0-3 m (via a guide and motive system), to accommodate the testing of different embankment heights.
Once locked in position, vertical forces will be generated by actuators spaced at 0,65 m centres along its length, meaning the beam must have sufficient vertical stiffness to allow for the precise and accurate control of actuators.
The actuators will mimic a high speed moving load by operating in sequence according to specifications (frequency and force).
The reaction beam will be supported by columns at each end.
The frame-to-beam connections require design, however the columns and their foundations will be designed separately by an alternative consultant as part of the civils work contract.
In-built craneage capability will be required to lift 5-10 t loads onto the embankment samples.
Control systems will be required for the crane, frame movement and hydraulic actuators.
A hydraulic power unit, piping and cooling is also required, the housing and service duct work will be supplied by the civils contract for the hydraulic power unit.
Data acquisition and cabling is needed to monitor future test samples.
All applications and contact must be made via the University's tendering portal - http://www.delta-esourcing.com/tenders/UK-UK-Leeds:-Railway-equipment./945NKN64WA
