Test bench architecture and modules
- Mechatronic integration of rear-axle steering systems,
e.g. via- Flexibly adjustable and close-to-application mechanical fi xtures for different types of rear-axle steering systems
- Integration of control devices, sensors and fi eldbus systems (CAN, FlexRay)
- Integration of test item and vehicle models
- Hydraulic actuator to test different forces and positions
- Counter force: ± 12 ... ± 25 kN
- Stroke: ± 150 ... 300 mm
- Adjustment speed: 500 ... 1000 mm / s
- 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 signal currents of the specimen actuator and ECU
- Forces, positions, angles, torques and temperatures
- Models and interface with real-time hardware (e.g. MATLAB / Simulink, dSpace)
- Robust design for functional tests and deployment in a testing environment
