Test Benches for Active Roll Control Systems

Fields of application

Engineering, optimization and validation of functions of electromechanic roll control systems
Analysis of static and dynamic characteristics
Parameter identification as a function of temperature
Simulation and validation of system behaviour in failure scenarios

Test bench architecture and modules

Highly dynamic mechanical loading devices
- hydraulic oder electrical servo-drives
- i.e.: + /- 20 kN; + /- 125 mm; + /- 4 m / s; 300 m / s²
- High lateral forces (+ /- 5 kN)
Electric supply for the specimen
- Capable vehicle power circuit emulation
- Recuperation by means of bi-directional power supplies
- Option: Battery switch for connection with battery simulators
Temperature control (i.e.: - 40 … + 140°C)
Measurement technology for
- Currents and voltages
- Forces, displacements and angles (for the entire temperature range between - 40 … + 140°C)

Automation

Force and stroke control for various load cases such as:
- Identification of static and dynamic stiffness
- Identifcation of command responses
- Identification of disturbance rejection
Model-integration capability, high scalability for functional extensions (e.g. fault-insertion)
Automated report generation with NI DIAdem
