dSPACE provides highly dynamic turn-key test benches for mechatronic components and systems. Our range of services covers all the tasks involved, such as concept design, planning, installation, implementation and support.
Matthias Deter is Group Manager Engineering, responsible for customer projects with mechanical test benches, at dSPACE in Paderborn, Germany.
In some hardware-in-the-loop (HIL) test cases, it is not possible to access the electronic control unit (ECU) only by its electric interfaces. Mechanical access is also indispensable for tasks such as:
With HIL technology, it is no problem to integrate and test ECUs (such as steering ECUs with all their interfaces) and vehicle buses. The reference values for the load machines are provided in real time by real-time simulation models. Genuine closed-loop operation between the test bench components, the ECUs and the simulation is achieved via suitable I/O interfaces. Thus, realistic load scenarios for the electronic and mechanical components can be created by coupling the test bench with a HIL simulator. Different load machines are used for different requirements and applications: rotary drives, spindle actuators, highly dynamic linear motors, etc.
These are typical test bench application areas:
Depending on the use case, the requirements comprise:
Designing, constructing and controlling test benches with the following main application areas:
