Modeling of the interaction of rigid wheels with dry granular media
, 2019 We analyze the capabilities of various recently developed techniques, namely Resistive Force Theory (RFT) and continuum plasticity implemented with the Material Point Method (MPM), in capturing dynamics of wheel--dry granular media interactions.

Unsteady effects during resistance tests on a ship model in a towing tank [PDF]
, 2008 It is known that there are oscillations in the wave resistance during the constantvelocity phase of a towing-tank resistance test on a ship model. In this work, the unsteady thin-ship resistance theory has been applied to this case. The results have been

The Research on a Confined Modeling Method of the Effect of Deformable Ground Soil and Crawler Board
MATEC Web of Conferences, 2018 There is a great relationship between the passing capacity of vehicles on the ground deformation road and the properties of confined and shear of ground soil, so it is necessary to establish a model that can reflect the soil pressure of the deformation ...

Journal of Field Robotics, Volume 43, Issue 3, Page 1884-1904, May 2026.ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.
