If the slope is 16°, load is 100N, and slip ratio increases from 0 to 0.6, the relative errors of predicting normal force, drawbar pull and driving torque between calculation values and experimental data are less than 10%. The model can predict wheel-terrain interaction mechanics effectively for a rover while climbing up slopes.

在斜坡角度为16°，载荷为100N，当滑转率从0增加到0.6时，将模型的车轮斜坡法向载荷、挂钩牵引力和驱动力矩的计算值与实验数据相对比，结果相对误差不超过10%，因而该爬坡模型可以有效地用于月球车轮地相互作用的力学计算。

From the mechanics analysis, the relationships between the configure parameters (such as the wheel parameters and the position of mass center) and the mobility performane indexes (such as the wheel sinkage, motion resistance and drawbar pull) are obtained. The design principles of the wheel parameters, position of mass center and the wheel space are given. It is demonstrated that the mass center is crucial to the mobility performance of the lunar rover.
