An Application of Plasticity Theory to the Solution of the Rigid Wheel - Soil Interaction Problem
1973PLASTICITY THEORY IS APPLIED TO THE ANALYSIS OF SOIL-WHEEL INTERACTION. THE PROBLEM IS REDUCED TO THE DETERMINATION OF STRESSES AT THE INTERFACE OF THE RIGID WHEEL AND THE SOIL. ONCE THESE STRESSES ARE KNOWN, THE WHEEL LOAD, TORQUE, PULL AND DRAG ARE OBTAINED BY INTEGRATING THE STRESSES ALONG THE WHEEL PERIMETER.

Modeling of wheel–soil interaction over rough terrain using the discrete element method
Journal of Terramechanics, 2013Abstract A numerical study was conducted using the discrete element method (DEM) to investigate the performance and mobility impacts of rough terrain operation for small unmanned ground vehicles. The DEM simulation was validated using experimental data from two types of single-wheel tests previously published in the literature: straight-line ...

Motion-control-based analytical model for wheel-soil interaction mechanics of lunar rover
Proceedings of 2011 6th International Forum on Strategic Technology, 2011During rover lunar exploration missions (such as China's “Chang'e”), rovers are required to move autonomously on the loose lunar soil. Control methods based on the rigidity hypothesis can hardly be expected to satisfy these requirements practically so wheel-soil interaction mechanics should be taken into account. The currently used integral model based

New rocker-bogie and terramechanics-based wheel/soil interaction models for planetary rovers
2012 IEEE International Conference on Mechatronics and Automation, 2012Mars rovers have to this point been almost completely reliant on the solar panel/rechargeable battery combination as a source of power. Curiosity, currently en route, relies on radio isotope decay as its source of electrical power. Given the limited amount of space available for solar panels and that the wattage available from radioisotope decay is ...
