Aerodynamic test applications

Windtunnel and vehicle dynamics testing

When testing (race) car aerodynamics in windtunnels, it is essential to simulate high speed on-road conditions. High pressure air bearings in moving ground systems (rolling roads) avoid upward suction of the belt in areas of rapid air movement and guarantee zero friction between belt and bearing. The air film stabilizes and cools the belt and thus reduces the drive power needed for the moving ground system.

Tyre test applications

Tyre force, torque, resistance testing

Understanding the behaviour of tyres and tyre mechanics is key to determining their influence on the ride, handling and safety of sport cars and commercial vehicles. Tyre testing is critical to conform to legislative requirements and to improve the overall tyre performance. Test set-ups with ultra high pressure air bearings, up to 25 bar, ensure friction free testing supporting high forces.

Torsion, torque and bearings measurement

From R&D to manufacturing and compliance testing, measurement and optimisation of powertrain performance not only requires progressively greater accuracies but also consistency in measurement over the specified ranges and conditions. Non-contact air bearings guarantee friction free rotational motion for torque test systems and bearing & seal measurements.

Acoustic test applications

Noise testing of interior parts, tanks, etc.

The noises emitted by assembled vehicles are the result of complex interactions. They vary during different movements in different conditions. Tuning out unwanted noise, vibration and harshness requires sophisticated test equipment. Noise emitted by air bearings is close to zero, making them ideal as silent motion systems in sound-proof chambers for vehicle testing.
