| Abstract | For estimation and control of the wheeled mobility of a lunar/planetary exploration rover, three-dimensional stress distribution measurements and a theoretical model of a rigid wheel on loose soil is quite important. We developed a single wheel testbed for use in comprehensive experiments, to understand the wheel-soil interaction, and measured the normal, circumferential, and lateral stress distributions beneath the wheel on lunar regolith simulant. These experiments yielded estimates of the shear stress direction and the soil flow directions, by combining the two-directional shear stress distributions. We validated the measurements by integrating the vertical components of the normal and shear stress distributions. The classical shear stress model was also compared with the measurements. We found no significant difference between the model and the measurements performed on lunar regolith simulant under three different slip conditions. |
