Abstract�� A tractive performance test-bed for wheel of planetary rover was designed and manufactured. Lunar soil simulation for wheel-soil experiment was prepared. Preparation of the lunar simulation on soil-bin was accomplished and mechanical properties of the in-situ lunar soil were remodeled. Tractive performance experiment for wheel of different lug types was conducted, based on which failure of lunar soil simulant and travelling resistance of wheel were analyzed. The results show that when increasing the wheel load, drawbar pull accordingly increase and the tractive efficiency show downtrend before uptrend. Drawbar pull also increase with the increase of lug height or lug number. In addition, there is little influence on the tractive performance while the wheel rotate speed changes among a lower range.
Keywords�� lunar rover vehicle   simulant lunar soil   wheel-soil interaction   tractive performance
