This test rig has been designed for torsional fatigue and static strength testing of drive shafts. The test specimen is subjected to specified loads and test set-ups in order to achieve the required number of cycles. The failure criteria are the attainment of defined torsional angles or the failure of the test specimen.

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.
