Test Benches for Active Roll Control Systems

Fields of applicatione

• 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
