Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Design of a hydromechanical transmission with regeneration for a passenger vehicle.
    (2012-09) Sedler, Stephen Joseph
    The design of a four-mode, input-coupled, power-split hydromechanical transmission with energy storage is presented. The focus of this thesis is on the design process of the transmission utilizing Lagrange multiplier optimization and machine design principles to construct the prototype transmission for use on a Polaris Ranger chassis. The four-mode design presented facilitates vehicle operation in hydromechanical power-split mode, parallel mode, and two series modes. An optimal mode of operation map is determined and a maximum fuel economy of 78.5 mpg is calculated.
