查询词典 planetary wheel

The deformation of the wheel was defined through finite element method, and according to analysis method for elastic tyre in terramechanics, the draw bar pull force of spring wheel on lunar soil was computed and compared with that of rigid wheel. The result shows that the spring wheel can improve the lunar rover mobility performance.
