Creating An Automatic Lowering Function For Quarter-Scale Tractor Pulling Sled, Sam Wilkins
Creating An Automatic Lowering Function For Quarter-Scale Tractor Pulling Sled, Sam Wilkins
Honors Theses
As the agricultural industry works to continuously integrate innovative technology and improve production efficiency, improved on-board data acquisition and transmission will be necessary for all agricultural machines. To make this a reality, the utilization of controller area network (CAN) technology will be crucial. Therefore, it is important for all agricultural engineers to have foundational knowledge of CAN bus systems and the standards that govern their use in industry. The UNL quarter-scale tractor team regularly utilizes CAN buses on their tractors and testing equipment. One such testing machine is the team’s pulling sled, which uses CAN messages to transport important information …
An Evaluation Of Tractors Tested At The Nebraska Tractor Test Lab And The Effect Of Epa Emission Standards Based Upon Average Pto Horsepower And Fuel Efficiency, Dalton Erickson
Honors Theses
Newly released tractor models are tested to ensure they meet advertising claims. This thesis utilizes tractor test data to analyze performance trends in tractors based upon their power take off (PTO) horsepower and fuel efficiency and it evaluates how the average fuel efficiency of tractors was affected by the introduction of emission standards by the United States Environmental Protection Agencies. In conclusion, tractors have shown continuous improvement and growth in both fuel efficiency and PTO horsepower, and emission standards have had a small, positive effect on tractors’ average fuel efficiency.
Development Of Controller Area Network Bus Programming For Quarter-Scale Tractor Pulling Sled, Brittani Wacker
Development Of Controller Area Network Bus Programming For Quarter-Scale Tractor Pulling Sled, Brittani Wacker
Honors Theses
Usage of Controller Area Network (CAN) technology has allowed for advancements in many industries, including agriculture. Most importantly, its application is useful for refining data acquisition methods. With support from the Quarter-scale Tractor Design Team at UNL, this project united a CAN bus with the team’s current tractor pulling sled. The objectives were to install new instrumentation needed for the CAN bus and to program the updated system utilizing CAN data. The program needed to give the pulling sled functionality and the ability to read and log important pulling data. These goals were all accomplished by implementing new sensors, coding …
