A test rig capable of producing compression loads of up to 3,600 kN and tensile loads of up to 2,200 kN by means of two hydraulic jacks each with a stroke of 800 mm. These loads can be applied and/or absorbed as reaction forces at the buffers, in the coupler, at the obstacle deflector or at different levels (floor, waist, longitudinal roof member, etc.) depending on the type of structure. Other smaller jacks can also be used to check the performance of the shock absorber supports or any other structural components.
During the tests, a large number of checks and measurements are conducted to ensure that the body shell is compliant with requirements. By way of example, mention can be made of the checks into surface flatness, measurement of compressive and tensile loads, micro-deformation using strain gauges, variations in deflection in the two sole bars and the longitudinal roof member, in body length, frame diagonals (windows, doors, traps).
We can also take charge of tool design and manufacture. This may require three-dimensional modelling of the structure on the rig.
Nos systèmes de mesure sont dotés de logiciel de dépouillement automatique permettant l’analyse des résultats en temps réel.
Our measurement systems are backed by software for automatic real-time processing of the results obtained. Where the logistics aspects are concerned, the structures to be tested can be delivered as outsize loads by road, or by rail. We have the necessary equipment for unloading at our testing plant.
In cases where the client is unable to send the service bogies with the structure to be tested, we can provide the requisite replacements for testing purposes.
