Abstract To solve the deflection problem of front-wheel-drive vehicle at high speed on chassis dynamo-meter, force characteristics and movement instability were studied. The axial force of blocking-wheel was selectively analyzed at different relative position between axle of blockingwheel and center of vehicle wheel after holding wheels. Based on SolidWorks platform, virtual prototype technology was applied to design the vehicle anti-deflection blocking-wheel to automatically adapt the position and diameter of vehicle wheel. The axial force on blocking-wheel was detected by sensor. The relative position between blocking-wheel axial and vehicle wheel center was identified to automatically position blocking-wheel with vehicle wheel. The vehicle deflection was prevented without slipping by blocking-wheels. The result shows that the proposed system can effectively realize pure rolling without vehicle deflection and without friction loss.
