Aufbau und Module des Prüfstands
Test bench architecture and modules
- Mechatronic integration of test items, e.g.
- Active and passive chassis components (e.g. active anti-roll bars, shock absorbers, wheel modules)
- Steering systems for front and rear axles and, if applicable, dynamic steering
- Relevant ancillary components
- Control devices, sensors and fi eldbus systems (CAN, FlexRay)
- Vehicle models
- Suitable drive transmission technology to test different forces and torques
- Electrical servo drives, linear cylinders and actuators
- Hydraulic actuators
- Powerful simulation of vehicle electrical systems incl. energy recovery
- Cut-off relay adaptor for highly automated simulations of electrical failures
- Metrology to record
- Control and power signals (Currents, voltages) of the specimen actuators and ECU’s
- Forces, torques, positions, angles, accelerations and temperatures
- Models and interface with real-time hardware (e.g. MATLAB / Simulink, dSpace)
