A/C roller test bench Ingolstadt

Our climatic roller test bench in Ingolstadt has been meeting the dynamic requirements of automotive development for years and, like the altitude climatic roller (HKR) in Berlin, offers the possibility of simulating test drives under extreme conditions.

The climatic chamber with roller test bench and sun simulation allows us to precisely simulate a wide range of environmental conditions and provide our customers with reproducible measurement results. Temperatures ranging from minus 30 to plus 55 degrees Celsius can be simulated on the state-of-the-art test stand and in two conditioning boxes. A driving wind blower generates realistic inflow of the test specimen with wind speeds of up to 130 km/h. With the aid of solar simulation, we can achieve an irradiance of up to 1,100 W/m2 on the entire vehicle and the components. On the test rig, solar irradiance can be combined with temperature and a relative humidity of up to 87 percent.

The all-wheel drive test stand, designed for vehicles ranging from the Polo to the Sprinter, can simulate a total mass of 4,000 kg. It can also simulate application measurements at freely definable driving cycles with gradients, such as on trials in Finland or on the Großglockner. Thanks to the direct workshop connection, short-term modifications to the vehicle between measurements, for example for component validations of different construction stages or concepts, can be implemented quickly.

For the support of customer measurements, we are equipped with current software tools, so we can autonomously perform measurements according to customer specifications under consideration of our guidelines. We are supported by remote tools, which we constantly optimize and adapt.
