Discrete Element Modelling of Soil Compaction of a Press-Wheel
AgriEngineering, 2021 Press-wheels are wheels designed to compact the soil above seeds in the “seed cover” region. Soil compaction, produced by the press-wheels of seeders, affects seedling emergence and early plant growth.

DESIGN AND EXPERIMENT OF SELF-PROPELLED SYSTEM FOR PADDY FIELD WEEDER BASED ON THE INTERACTION MECHANISM OF WHEEL-SOIL [PDF]
Engenharia Agrícola, 2022 Aiming at the low mechanization of paddy field weeding and lack of dedicated agricultural machinery for paddy field weeding in China, a self-propelled system of paddy field weeding machine was designed. The overall structure and working principle of self-

Wheel rolling on deformable ground with slippage [PDF]
E3S Web of Conferences, 2022 Wheeled vehicles can move not only on a solid supporting surface, but also on deformable surfaces (snow, ground, sand, etc.). When a pneumatic wheel with a high internal air pressure rolls over deformable soil, the nature of the wheels’ interaction with ...

Simulation of the Wheel-Surface Interaction Dynamics for All-Terrain Vehicles
Applied Mechanics, 2022 In this paper, a new methodology for the numerical simulation of the wheel–surface interaction has been presented. The finite-element method was combined with the discrete-element method, rigid body dynamics, and the advanced wheel–surface friction model.

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.

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.
