Evaluation Of Foldable Tractor Roll-Over Protective Structures (Rops) Clearance, Luke Martin
Evaluation Of Foldable Tractor Roll-Over Protective Structures (Rops) Clearance, Luke Martin
Pursuit - The Journal of Undergraduate Research at The University of Tennessee
Tractor rollovers are a leading cause of death in the agricultural industry. While rollovers continue to happen, Roll-Over Protective Structures (ROPS) have shown great ability to prevent or reduce the casualties and injuries associated with rollover events. One authority on the subject even goes so far as to claim that “that fatality rates due to tractor overturns could be reduced by a minimum of 71% if all tractors in the U.S. were equipped with ROPS,” (NIOSH, 2009). The potential of this promising statistic has been devalued slightly due to the misapplication of foldable ROPS by leaving the ROPS in the …
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 …
