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
