摘要: 设计搭建了深空探测车车轮牵引特性试验台,制备了轮土试验用模拟月壤,在土槽中进行了模拟月壤的整备,重塑了就位月壤的力学特性.对不同轮齿类型的刚性车轮进行了牵引特性试验,分析了轮下模拟月壤的剪切破坏和车轮行驶阻力的表现形式.结果表明:增大轮上载荷能够提高挂钩牵引力,车轮的牵引效率随着滑转率的增加呈现先增加后降低的趋势;随着轮齿高度的增加,挂钩牵引力会随之增大,车轮的最大牵引效率有所降低;随着轮齿数目的增加,挂钩牵引力会随之增大,车轮的牵引效率变化不大;车轮转速在数值较低的范围内变化时,对牵引性能的影响较小.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.
