Capability Statement

Our tests and test quantities: Measurements for vehicles – Aerodynamic loads for passing rail traffic in the open and in a tunnel, e.g. bow wave, flow loads, pressure signature in tunnel – Special topics such as driving resistance, undercarriage aerodynamics, pantograph aerodynamics, specific design specification verifications Measurements for infrastructure components – Response of movable and immovable objects as a reaction to aerodynamic loads from passing rail vehicles, e.g. the reaction of noise barriers, platform canopies, signalling installations, switch cabinets, fixed track work barriers, movable items on platforms (luggage trolleys) and bridge inspection vehicles – Special topics such as flying ballast Tunnel and underground stations – Commissioning measurements, e.g. increase in pressure waves on entry – (Sonic boom) and pressure loads with reactions to emergency doors, cover plates, equipment rooms or equipment cabinets – Pressure loads when two trains meet each other under controlled conditions – Ventilation of tunnel constructions – Comfort considerations with respect to flow and ventilation conditions and meteorological constraints (temperature, humidity, ambient pressure) Measurement of aerodynamic loads in railway application areas – Differential pressures in measurement range up to ± 7,000 Pa – Flow speeds up to 90 m/s – Forces in measurement range up to ± 10,000 N – Distances in measuring range of 0.1 mm up to 1 km – Deflections in measuring range up to ± 100 mm – Acceleration in measuring range up to 10 g Measurement of meteorological influencing factors and constraints – Temperatures in measuring range -40°C to +60°C – Humidity up to 100% (RH) – Absolute pressure in measuring range of 800 hPa to 1,100 hPa. – Wind speeds in measuring range up to 60 m/s – Wind directions in measuring range up to 360° – Train speeds up to 400 km/h Measurement in wind tunnel tests conducted for rail vehicles and systems – Forces in measuring range up to ± 5,000 N – Torque applications in measuring range up to ± 500 Nm – Differential pressures in measurement range up to ± 7,000 Pa- .
