Comparative Analysis of Non-Pneumatic Tire Spoke Designs for Off-Road Applications: A Smoothed Particle Hydrodynamics Perspective

Geotechnics
This study explores the development of a terramechanics-based model for non-pneumatic tire–terrain interaction, focusing on different spoke designs. The research investigates how four spoke shapes (honeycomb, modified honeycomb, re-entrant honeycomb, and

Variaciones del índice de cono en suelo movilizado posterior al tráfico de un tractor equipado con dos tipos de neumáticos y a cuatro velocidades de desplazamiento [PDF]

, 2007
The tractor is one of the machines that more traffics over the soil during the processes involving agricultural production. The interaction tractor/soil is made by the tires which, in most of the cases, are pneumatic. The tire type and the tractor travel

Traction characteristics and failure mechanisms of deep-sea ultra-soft sediment under grouser shear

Applied Ocean Research
Traction performance is a critical factor governing the robust operation of deep-sea tracked mining vehicles on ultra-soft sediments. However, classic terramechanics models, such as the Bekker and Wong formulas, systematically underestimate traction ...

Investigation of full scale track–seabed shear interaction: the saturated soft clay traction model for deep–sea mining vehicle mobility

Applied Ocean Research
Tracked deep–sea mining vehicles frequently suffer from excessive slippage and sinkage on soft seabeds, which compromises their operational mobility. Conventional terramechanics models, rooted in terrestrial soil behavior, fail to capture the profound ...

Terramechanics and Machine Learning for the Characterization of Terrain

, 2020
An instrumented rover wheel can collect vast amounts of data about a planetary surface. Planetary surfaces are changed by complex geological processes which can be better understood with an abundance of surface data and the use of terramechanics. Identifying terrain parameters such as cohesion and angle of friction hold importance for both the rover ...
