基于大地力学和被动土压力理论，建立了月球车刚性车轮在滚动和转向过程中车轮-土壤相互作用的力学模型。分析了牵引杆拉力、滚动扭矩、转向扭矩等不同土壤参数对刚性车轮的力学影响。在力学参数与月壤相似的干燥土壤中对刚性车轮的试验结果验证了模型的正确性。设计了用于月球车轮土相互作用性能测试的新型试验台及其数据采集系统，并对其中的关键技术进行了讨论。
Mechanical models of the wheel-soil interaction are constructed for a rigid wheel of lunar rover when rolling and steering, based on the theories of terramechanics and passive earth pressure. The mechanical affect of different parameters of the soil to the rigid wheel is analysed, such as drawbar pull, rolling torque and steering torque. Experimental results of a rigid wheel in a kind of dry soil, whose mechanical parameters are some similar to lunar soil, validate the models correct. A novel test-bed and its data acquisition system are also designed for testing the performance of the wheel-soil interaction of lunar rover, and their key technologies concerned are discussed.
