  1. 6 Degrees of Freedom Chassis dynamometer

  2. Application • Simulate real rolling conditions • Interchangeable flat road surface • Compact environment • High speed rolling • Simulation of any road condition • Grip loss test under different vertical load conditions • Slip angle test • Tire property validation • Lateral force • Classical chassis dynamometer test

  3. General Architecture: Chassis dynamometer • Simulation of traction force with road profile at the required speed • Flat belt system • Driven by asynchronous motor • Actuators to provide self aligning torque

  4. General Architecture: Chassis dynamometer • High pressure air bearing to limit friction and heat effect • Design for easy access on specimen • Choose your road surface OPTION: Vertical shaker: (±1 mm @ 100 Hz)

  5. General Architecture: 6DoF actuator • 6 hydraulic actuators close-loop controlled for any road conditions • Control in force (vertical, lateral) or in position (pitch, yaw, roll angle)

  6. General Architecture: 6DoF actuator

  7. General Architecture: Hydraulic actuators • Hydraulic actuator with hydrodynamic bearings. • Double ended, one piece piston rod. • Servo-valve manifold equipped with 2-stage servo-valve and optional configurable security valves • Internal LVDT (displacement transducer) • Ball-joint (swivel) at top of piston rod • Ball-joint (swivel) for actuator base. • Controlling and measuring cables

  8. Measurement system • Measurement on our bench • Loads and displacements for the 6 dof. • Flat road speed • of your parameters • Dedicated system for any application

  9. Control System: BMC800 • Enables close loop control of all electric&hydraulic actuators • Management of logical axis • Integrates • Digital conditionners • Real time acquisition for AC/DC sensors (up to 10kHz)

  10. Software: UTM • Prepare your test • User friendly environment • Drag&drop programming • Test & control • Create cusomized control screens for test monitoring • Real time display • Postprocessing • FFT analysis, calculations, test reports…
