| 摘 要： | 以重塑模拟月壤为介质,利用深空探测车车轮牵引特性实验台,研究了月面巡视探测器的刚性轮齿车轮与模拟月壤的交互作用,分析了车轮转速、轮上载荷等试验因素对车轮牵引通过性的影响.研究结果表明,当车轮转速较低时,挂钩牵引力随滑转率的增加而不断提高;当车轮转速较高时,存在着临界滑转率点.轮上载荷的增加有利于提高车轮的挂钩牵引力,但对挂钩牵引力系数的影响较小. |

| 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 in... |
| Keywords: | lunar rover vehicle lunar simulant wheel-soil interaction tractive trafficability |
