The NVH test rig measures noises, vibrations and harshness (NVH = Noise Vibration Harshness). Drive shafts generate forces that simulate the load conditions in the car as they would occur on the road.

NovoPS test-stand software

The NovoPS test-stand software is a Windows-based solution that is programmed in-house and optimised for the respective test task. As the interface to the user, the uncomplicated user interface provides intuitive access to all functions of the test stand. Moreover, both the connection of the test stand to the customer's conveyor systems as well as its integration into the existing network environment is taken into account. This enables the data acquired to be processed and evaluated independently of the test stand.
