A Finite Element Model of Soil-Stress Probe Interaction under a Moving Rigid Wheel [PDF]

open access: yesJournal of Agricultural Machinery
Machinery 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.

Investigation of the Effects of Tire Inflation Pressure and Forward Speed of Driven Wheel on Horizontal Impact of Passing Rectangular Obstacle

open access: yesJournal of Agricultural Machinery, 2013
The tire-mechanics models have been developed for the study of wheel movement on the road or soil surface while these models are unlikely to describe the motion of wheels on uneven surfaces.

Analysis of traveling wheel on loose sandy soil (Sandy soil flow beneath a wheel due to the interaction)

open access: yesNihon Kikai Gakkai ronbunshu, 2017
Soil-vehicle interaction is an important factor for predicting trafficability of off-road vehicles. Tractive forces on the wheel to drive the vehicle can be estimated by soil deformation analysis around the contact area of the wheel. Sand deformation and

Predicting the wheel rolling resistance regarding important motion parameters using the artificial neural network [PDF]

open access: yesJournal 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.

Application of artificial neural networks for the prediction of traction performance parameters

open access: yesJournal 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

open access: yesScientific 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

open access: yesMachines
The 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

open access: yesNihon 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.

Experimental research of planetary rover entrapment on sandy terrain

open access: yesResults in Engineering
Trafficability of wheeled rovers on loose and rough terrain is essential for planetary exploration missions. Existing studies mainly focused on wheel–soil interaction modeling, terramechanics simulation and motion control, yet full-vehicle experimental ...

Development of Grousers with a Tactile Sensor for Wheels of Lunar Exploration Rovers to Measure Sinkage

open access: yesInternational Journal of Advanced Robotic Systems, 2014
This paper presents a grouser developed for the wheels of lunar exploration rovers to measure sinkage. The wheels, which are intended to traverse loose soil such as lunar regolith, contain grousers that transfer thrust to the wheels and thus to the body ...
