  • A methodology for iterative design using physical test data

    Creator:
    Morris, Wesley T.
    Abstract:
    This thesis addresses a common knowledge gap that was identified amongst the Society of Automotive Engineers (SAE) competition design teams at Oregon State University. Students that join the SAE teams at Oregon State University typically do not have experience using physically collected data during a design process. This leads to...

  • Alternative design considerations for a wave energy converter : a sustainability approach

    Creator:
    Collins, Erin
    Abstract:
    As the negative impacts of a fossil fueled electricity market are becoming more prevalent and destructive, the necessity for alternative energy techniques increases as well. However, before commercial implementation is underway, these alternatives must be assessed from three important perspectives: environmentally, economically, and socially, which are known as the three...

  • The fracture toughness of medium density fiberboard and other fiber bridging composites

    Creator:
    Matsumoto, Noah T.
    Abstract:
    In many composites, fiber bridging develops as part of the fracture process. Fiber bridging invalidates many toughness evaluation methods such as the ASTM E399 and complicates the identification of crack length, which is a necessary parameter in energy methods. In order to measure the toughness of fiber bridging composites, an...

  • Advancing Wind Systems Design through Optimization and Improved Modeling

    Creator:
    Miller, Annalise M.
    Abstract:
    Wind energy plays an important and growing role in the US energy profile. While other countries have expanded their wind industries into offshore development, large investment costs have hindered progress in the US offshore market despite the larger and more consistent resource available offshore. In this research, I explore the...

  • Knowing your customers : ontological gathering and analysis techniques

    Creator:
    Nix, Anthony A.
    Abstract:
    This research presents a methodology to analyze customer needs and direct the gathering of customer needs that both span the need space and are independent. An ontological categorization, the fundamental research contribution of this work, is created to support both aims of the overall methodology. Providing designers with a customer...

  • Wave Energy Converter Array Optimization : Algorithm Development and Investigation of Layout Design Influences

    Creator:
    Sharp, Christopher J.
    Abstract:
    Realizing the vast amount of energy available in ocean waves, an industry has emerged that is progressing towards the deployment of grid–connected wave energy converters. Likely to be deployed in arrays, a challenge to the wave energy industry is maximizing the energy production of such arrays. We have been developing...

  • The Mira 2 Rocket Engine: Applying Lessons Learned for an Improved Iteration

    Creator:
    Dimas-Harms, Colton R.
    Abstract:
    In this paper, I present the design of Mira 2, a small-scale, liquid bipropellant rocket engine, with a specific focus on its oxidizer-centered pintle injector. Building upon the valuable lessons and insights gained from the empirical testing of its predecessor, Mira 1, the Mira 2 engine incorporates several improvements and...

  • Effect of lateral force on passenger comfort during a mechanically assisteddependent transfer

    Creator:
    Mast, Jonathan J.
    Abstract:
    Air travel presents several problems for passengers with disabilities. One in particular is how they get from their wheelchair and to an aircraft seat. The commonly used manual transfer method is hazardous to the assistants and the passenger. There are other alternatives, but they have plenty of room for improvement....

  • Micro adiabatic combustion engine : concept development, simulation and combustion experiments

    Creator:
    Chewning, Scott R.
    Abstract:
    The current proliferation of portable electronic devices for personal communication, business and entertainment has created a demand for high energy density power supplies. A hydrocarbon fuel with a conversion efficiency of over 15% can provide greater energy density than current battery technology for these applications. Current micro-scale heat engines do...

  • Passive dynamics and their influence on performance of physical interaction tasks

    Creator:
    Kemper, Kevin C., II
    Abstract:
    For robotic manipulation tasks in uncertain environments, research typically revolves around developing the best possible software control strategy. However, the passive dynamics of the mechanical system, including inertia, stiffness, damping and torque limits, often impose performance limitations that cannot be overcome with software control. Discussions about the passive dynamics are...
