Predicting Agricultural Implement Hydraulic Power Demand Using Synchronized Controller Area Network And Ancillary Sensor Data, Gabriel P. Stoll
Predicting Agricultural Implement Hydraulic Power Demand Using Synchronized Controller Area Network And Ancillary Sensor Data, Gabriel P. Stoll
Department of Biological Systems Engineering: Dissertations and Theses
As agricultural implement designs have progressed in recent years, there has been an increase in hydraulic power demand from the tractor. Current power estimation standards do not accurately estimate hydraulic power demand for implements designed with higher hydraulic power requirements. Several stakeholders, including agricultural producers, tractor and implement manufacturers, and government agencies would benefit from accurate published data on these power requirements.
While an increasing amount of operational data available on the Controller Area Network (CAN) of tractors has assisted researchers in more easily obtaining machinery performance data, hydraulic control valve flow rate and pressure measurements are not currently publically …

Effect Of Limited Water Supplies On Center Pivot Performance, Derrel Martin, Derek M. Heeren, Steve Melvin, Troy Ingram
Department of Biological Systems Engineering: Conference Presentations and White Papers
When appropriately designed and operated, center pivot irrigation systems can efficiently irrigate many crops grown on diverse soil and terrain conditions. However, a significant number of pivots are not supplied with an adequate water to operate as envisioned.
We simulated the hydraulics of a center pivot irrigation system, including the pump curve, flow rate, pipeline hydraulics, pressure regulators, nozzle flow rate, and irrigation application uniformity. This was used to analyse the performance of a center pivot for a sloping field for both adequate and inadequate water flow rate. The performance was simulated for a range of inlet pressures when pressure …
