About the system

The tire-coupled road simulator places the vehicle on servo-hydraulic actuators under its wheels (4 or 6 posts) and reproduces measured road data in the laboratory. Durability, ride comfort, BSR (buzz-squeak-rattle) and NVH tests can also run inside a climatic chamber. With 2, 3 and 6-axle configurations it tests vehicles from 2.5 t passenger cars to 30 t heavy trucks, with multi-level protection for operator and specimen safety.

Technical scope

  • Vehicles 2.5–30 t
  • ±38–200 kN actuators
  • 0–100 Hz

Test functions and capabilities

  • Durability with road-data iteration
  • Ride comfort
  • BSR and NVH
  • 2/3/6-axle configurations
  • Climatic chamber option
  • Operator and specimen safety system
