  • Direct-sampling optical techniques for the study of transient combustion events

    Creator:
    Herron, John R.
    Abstract:
    Techniques have been developed for measuring the temperature, stable species concentrations, and atomic radical concentrations during a transient combustion event. They combine the features of direct sampling with two spectroscopic techniques to produce relatively simple diagnostic techniques to obtain time-resolved measurements. In this study, a transient event was provided by...

  • Reverse engineering, modeling, and redesign of a vibratory conveyor

    Creator:
    Foglesong, Timothy J.
    Abstract:
    Some successful products are still developed and produced without the benefit of modern design techniques. One such product is a vibratory conveyor that has been developed largely through prototype iteration. The manufacturer has collaborated with Oregon State University to introduce model-based design into the development process. This research details a...

  • Aircraft wing optimization using B-spline models and panel methods

    Creator:
    Jackson, Danielle Monique
    Abstract:
    This research investigates shape optimization process, using b-spline models and panel methods, to achieve a high lift to drag ratio for an aerodynamic structure. This research is a proof of concept for further research in aerodynamic shape optimization. The coupled process, involving the design and optimization of a random shape,...

  • Systematic design of biologically-inspired engineering solutions

    Creator:
    Nagel, Jacquelyn Kay
    Abstract:
    Biological organisms, phenomena and strategies, herein referred to as biological systems, provide a rich set of analogies that can be used to inspire engineering innovation. Biologically-inspired, or biomimetic, designs are publicly viewed as creative and novel solutions to human problems. Moreover, some biomimetic designs have become so commonplace that it...

  • Reduced order modeling of legged locomotion in the horizontal plane

    Creator:
    Wickramasuriya, Gamika Arun
    Abstract:
    Sprawled-posture insects exhibit a remarkable ability to rapidly run in a stable manner over complex terrain, a feat that has yet to be equaled by man-made legged robots. Recent experimental results suggest that these insects may employ a hierarchical control structure, in which locomotion performance emerges from a combination of...

  • Brake-based wheel speed control design of a rear wheel open differential vehicle

    Creator:
    Jeon, Eli
    Abstract:
    A brake-based wheel speed control system for a rear-wheel drive vehicle is developed and simulated in this thesis. The OSU mini-Baja vehicle team will use this study in the development and implementation of a similar system for upcoming competitions. Vehicle submittals must differ to a specified degree from previous year’s...

  • Learning approaches for the early detection of kickback in chainsaws

    Creator:
    Arnold, Drew D.
    Abstract:
    Among the many safety hazards facing chainsaw operators, the phenomenon known as kickback is the most dangerous. Kickback occurs when the chain at the tip of the chainsaw is caused to stop abruptly, and transfers the energy of the cutting chain to motion of the saw. The saw will rotate...

  • Design, analysis, and validation of composite c-channel beams

    Creator:
    Koski, William C.
    Abstract:
    A lightweight carbon fiber reinforced polymer (CFRP) c-channel beam was previously designed using analytical theory and finite element analysis and subsequently manufactured through a pultrusion process. Physical testing revealed the prototype did not meet the bending and torsional stiffness of the beam model. An investigation revealed that the manufactured prototype...

  • The dynamic shear moduli of blubber for selected large whale species

    Creator:
    Summers, Michael P.
    Abstract:
    Whale blubber is the insular tissue layer located between the dermis and the superficial fascia layer which sheathes the whale's musculature. It is made up of a lipid matrix ramified with strong, structural collagen and elastic fiber bundles, but little is known of its mechanical properties. Knowing these properties adds...
