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.

该发明主要由转子、轮轴，弯曲轨道三项组成。拉力绳在轮子上，当绳子拉动时，另一边在轮面半径中心安装的轮轴沿着和轮子半圆一样大的轨道卷动绳提起重物。

The computation model of two-point contact (for cone-tread) and conformal contact (for worn-tread) resulting from wheel flange close to rail is firstly established in this paper. A detailed analysis is made of the wheel/rail contact force, contact status and wheel/rail stress distribution on the different action of tractive forces and transverse forces. We draw some important conclusions, one of which is that the locomotive adhesion performance will decrease with the increase of transverse forces between wheel and rail.
