Abstract�� Based on a tractive performance test-bed for planetary rover wheel, remodeled lunar simulant as a medium, the interaction between the rigid lugged wheel of lunar rover vehicle and lunar simulant was studied. The influence on trafficability which are brought by rotating speed and wheel load, was analyzed. The results show that drawbar pull boosts with the increase of slip ratio as wheel runs at low speed; however, there is a critical slip ratio point for drawbar pull as wheel travels at high speed. In addition, an increase of wheel load leads to an increase of drawbar pull, whereas it influences the drawbar pull coefficient negligibly.
