Tyre / soil interaction modelling within a virtual proving ground environment [PDF]
, 2012 Off-road mobility defines the ability of land-based vehicles to accelerate, pull loads and climb gradients. Historically, much of the work completed to relate mobility to vehicle and terrain characteristics has been empirical in nature, and has ...

Impact of vertical load, multiple passes, and speed on rut depth in soil under pneumatic and track wheels [PDF]
Scientific ReportsWhen vehicles pass over soil, ruts are created in the soil, the effect of which can be found in soil compaction. This research was conducted to investigate and rank the effect of vertical load, multiple passes, and forward speed on rut depth.

Application of artificial neural networks for the prediction of traction performance parameters
Journal of the Saudi Society of Agricultural Sciences, 2014 This study handles artificial neural networks (ANN) modeling to predict tire contact area and rolling resistance due to the complex and nonlinear interactions between soil and wheel that mathematical, numerical and conventional models fail to investigate

Experimental identification of wheel-surface model parameters: various terrain conditions
Scientific Reports, 2022 Since the wheel interaction with a certain terrain cases (asphalt, concrete) are known and well described in case of straightforward motion and non-slip and slip cornering conditions, the skid-steered wheeled vehicles case needs to be analyzed. Side-slip

Parameters Identification of Tire–Clay Contact Angle Based on Numerical Simulation
MachinesThe predictive accuracy of the Bekker–Wong model for wheel traction is highly dependent on the precision of the wheel–soil contact angle parameters. These parameters are typically identified through extensive and costly single wheel–soil tests, which are

Evaluation of the shear deformation model in the process of wheel sinking by the wheel experiment
Nihon Kikai Gakkai ronbunshu, 2015 Soft soils cover on planetary surfaces, so the wheels for exploration rovers easily slip. Understanding an interaction between a wheel and soft soils is important for a traction control to improve rover traversability.
