Vehicle Structure Tests

Contribute to the type approval process of steel rolling stock by checking its resistance.

Tests objectives :

Check if rolling stock built with steel frames (wagons, locomotives, cars) can resist operating conditions

• Conduct tension, compression and pressure tests
• Simulate lifting and torsion
• Perform simulations with different loading conditions
• Conduct tests with specific loads

Tests facilities :

• Lifting track: Loads consist mainly of ballast. Lifting is done with four lifting cylinders (at one or both ends) or at two opposite corners (torsion test)
• Tension/compression test rig: Two cylinders are used to apply compression forces up to 3,600 kN and tension forces up to 2,200 kN
• Strain gauges for strain measurements
• Gauge sensors for measuring forces
• Comparators used for deformation measurements

Measuring the torsional stiffness of a vehicle body structure to ensure railway operating safety.

Tests objectives :

Determine the torsional stiffness of a vehicle structure around its longitudinal axis – for all types of vehicles: Trailers, rail vehicle frames, containers and swap bodies, road trailers

Tests facilities :

• Lifting cylinders
• Force and displacement sensors
