Blast mines: physics, injury mechanisms and vehicle protection. [PDF]
, 2009 Since World War II, more vehicles have been lost to land mines than all other threats combined. Anti-vehicular (AV) mines are capable of disabling a heavy vehicle, or completely destroying a lighter vehicle.

Path Planning for Reconfigurable Rovers in Planetary Exploration [PDF]
, 2017 This paper introduces a path planning algorithm that takes into consideration different locomotion modes in a wheeled reconfigurable rover. Power consumption and traction are estimated by means of simplified dynamics models for each locomotion mode ...

A Finite Element Model of Soil-Stress Probe Interaction under a Moving Rigid Wheel [PDF]
Journal of Agricultural MachineryMachinery traffic is associated with the application of stress onto the soil surface and is the main reason for agricultural soil compaction. Currently, probes are used for studying the stress propagation in soil and measuring soil stress.

Improving safety of runway overrun through the correct numerical evaluation of rutting in Cleared and Graded Areas [PDF]
, 2014 Aircraft overrun is potentially very dangerous to human life. Statistics show that overrun is mainly due to human errors causing loss of control in wheel alignment, high approach speed, and long touchdown.

Predicting the wheel rolling resistance regarding important motion parameters using the artificial neural network [PDF]
Journal of Agricultural Machinery, 2016 Introduction: Rolling resistance is one of the most substantial energy losses when the wheel moves on soft soil. Rolling resistance value optimization will help to improve energy efficiency.

Soil Compaction Effects on Root-Zone Hydrology and Vegetation in Boreal Forest Clearcuts [PDF]
, 2019 Soil compaction is a common consequence of forestry traffic traversing unprotected, moist soils; it decreases porosity and affects hydraulic conductivity even in coarse-textured soils. The aim here was to study root-zone hydrology and vegetation in three

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
