The Report, Biomass as Feedstock for a Bioenergy and Bioproducts Industry: The Technical Feasibility of a Billion-Ton Annual Supply (generally referred to as the Billion-Ton Study or 2005 BTS), was an estimate of “potential” biomass within the contiguous United States based on numerous assumptions about current and future inventory and production capacity, availability, and technology. In the 2005 BTS, a strategic analysis was undertaken to determine if U.S. agriculture and forest resources have the capability to potentially produce at least one billion dry tons of biomass annually, in a sustainable manner—enough to displace approximately 30% of the country’s present petroleum …

Experimental Characterization And Modelling Of Energy Efficient Fluid Supply Systems, Karina M. Bjorklund, Andrea Vacca, Timothy J Opperwall

The Summer Undergraduate Research Fellowship (SURF) Symposium

In applications such as in agriculture, construction, and aerospace applications, high pressure hydraulics is the preferred technology to transmit mechanical power. As a consequence, the energy efficiency of the hydraulic system used to perform the mechanical actuations is of primary concern to reduce the energy consumptions in the abovementioned applications. In an hydraulic system, the primary component determining the energy efficiency is the hydraulic pump. This work focuses on the study of a particular pump design, also referred as external gear pump, particularly used in applications in which the cost of the hydraulic system has to be minimized. The large …

Controller Area Network (Can) Bus J1939 Data Acquisition Methods And Parameter Accuracy Assessment Using Nebraska Tractor Test Laboratory Data, Samuel E. Marx

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Electronics have become a standard in agricultural equipment and the trend of “smarter” equipment is on the rise. To have “smarter” equipment, a working knowledge of the accuracy of the data being transmitted throughout that equipment is needed. The controller area network (CAN) bus is the current interface to machine operation data transmitted between electronic control units (ECUs).

Because CAN bus has been around for nearly thirty years, numerous devices have been created for interfacing with the bus. Choosing a device can be a challenge, especially without knowing if there are differences between the logging methods for true data representation. …

Smart V-Belt, Kyle J. Mosier

Open Access Theses

The purpose of this research was to develop a method for detecting premature failure in a v-belt using capacitance and resistance readings. Another goal of the research was to detect tension values on the belt using the same readings. Materials of current belts and possible materials for a prototype belt were tested. Materials were chosen, and prototype belts were built. Pulley system configurations were developed and built. Sections of the belt designs were tested for capacitance and resistance before and after various methods of damage. Capacitance was chosen as the better sensing method. Certain layered belt configurations and sheave configurations …
