Abstract:
A challenging problem faced by wheeled mobile robots (WMRs) such as planetary rovers traversing loose sloped terrain is the inevitable longitudinal slip suffered by the wheels, which often leads to their deviation from the predetermined trajectory, reduced drive efficiency, and possible failures. This study investigates this problem using terramechanics analysis of the wheel-soil interaction. First, a slope-based wheel-soil interaction terramechanics model is built, and an online slip coordinated algorithm is designed based on the goal of optimal drive efficiency. An equation of state is estab

Abstract:
A review of terramechanics terrain models and discuss on their application in link-terrain, wheel-terrain and tire-terrain interaction are taken. Three kinds of pressure–sinkage relationship proposed by Bekker and Reece are studied. The loading and unloading is introduced in the model. And the relationship between the maximum shear stress and applied normal pressure is derived. The link tractive effort and drawbar pull at a given slip of an assumed shape and mass are deduced. Also the link moves in two dimensions. At last, the relationship of terrain sinkage vs. time, terrain pressure vs. sink

Abstract:
This thesis aimed to develop deformable a virtual terrain which a vehicle can move in and interact with in a realistic manner. The theory used to calculate how the terrain influences the vehicle is based on terramechanics. The terrain is divided into two separate parts, one for visualization and one for physical collisions. Deformations of the graphical layer is calculated on the GPU using compute shader programming. The result of the thesis include a tech demo with a small landscape where an alternate terrain vehicle can deform the terrain as it moves around. The method for deforming the grap

Abstract:
Pneumatic tire friction on ice is an under-researched area of tire mechanics. This study covers the design and analysis of a series of pneumatic tire tests on a flat-level ice road surface. The terramechanics rig of the Advanced Vehicle Dynamics Lab (AVDL) is a single-wheel test rig that allows for the experimental analysis of the forces and moments on a tire, providing directly the data for the drawbar pull of said tire, thus supporting the calculation of friction based on this data. This indoor testing apparatus allows for some degree of replication by helping to maintain test conditions

Mechanical systems always operate under some degree of uncertainty, which can be due to the inherent properties of the system parameters, to random inputs or external excitations, to poorly known parameters in the interface between different systems, or to inadequate knowledge of the dynamic process. Also, mechanical systems are large and highly nonlinear, while the magnitude of uncertainties may be very large.

Scientists have been well aware of the complexity of Martian and lunar regoliths. There are vast unexplored areas on both, the Moon and Mars, as well as uncertainties in our understanding of the physicochemical properties of their regoliths. Lunar and Martian regoliths differ from terrestrial soils in that they appear granular, but are expected to contain some cohesion. As such, cohesion in regolith poses challenges for future space operations, more specifically for landing, settlement, and mobility purposes.

Accurate and efficient tire models for deformable terrain operations are essential for performing vehicle simulations. Assessment of the forces and moments that occur at the tire-terrain interface, and the effect of the tire motion on properties of the terrain are crucial in understanding the performance of a vehicle. In order to model the dynamic behavior of the tire on different terrains, a lumped mass discretized tire model using Kelvin-Voigt elements is developed.
