Vehicle Multi-Pass Rut Volume And Mobility Power Study, William W. Barbour
Vehicle Multi-Pass Rut Volume And Mobility Power Study, William W. Barbour
Pursuit - The Journal of Undergraduate Research at The University of Tennessee
This paper presents the relationship between applied power by a wheeled vehicle to soil and the rutting effects. Specifically, a strong positive relationship was found between cumulative applied power and total rut volume across multiple passes by the vehicle over the same tracks. Field-testing was conducted using a high-mobility multi-purpose wheeled vehicle (HMMWV) and two distinct soil types. Sensors on the vehicle measured torque and angular velocity of each of the four wheels, from which applied power was calculated. A rut profile meter was used to document the shape of the rut after set numbers of passes and this profile …
