  • 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...

  • Numerical Modeling of Powder Metallurgy Hot Isostatic Pressing

    Creator:
    Sobhani, Samaneh
    Abstract:
    Powder Metallurgy Hot Isostatic Pressing (PM-HIP) is a widely recognized powder metallurgy manufacturing process to produce near-net-shape and net-shape components. During general PM-HIP processes the metal powders are filled within a capsule (die), heated and loaded with high pressure simultaneously, and solidified to form the final product. Due to the...

  • Dividing Complex Parts into Multiple Pieces for Advanced Joining and Additive Manufacturing

    Creator:
    Massoni, Brandon R.
    Abstract:
    Poor material utilization is inherent to conventional manufacturing processes, leading to high material waste and machining times. Additive manufacturing processes attempt to solve this issue by allowing production of near-net shapes, but the processes may be too expensive or infeasible. By leveraging both processes in a single part, the waste...

  • Synthetic Lubricant Performance in Enclosed Gearbox Applications at Extreme Temperature

    Creator:
    Marr, Carter J.
    Abstract:
    The goal of this paper is to evaluate how synthetic lubricants perform in an enclosed gearbox application when compared with a proven mineral oil. This is in an effort to improve gearbox efficiency with the desired effect of lower emissions from of improved energy output from power generation. Four liquid...

  • Automated decomposition of complex parts for manufacturing with advanced joining processes

    Creator:
    Massoni, Brandon R.
    Abstract:
    Recent advancements in joining operations and additive manufacturing now allow complex metal parts to be built up from raw materials, as opposed to being machined down from solid blocks. This not only opens up the design space, but also allows for much more efficient manufacturing. By decomposing a complex part...

  • A design framework for identifying automation opportunities

    Creator:
    Nagel, Robert Lewis, 1982-
    Abstract:
    Since the Industrial Revolution, automated systems have increasingly become a part of everyday life. Automated systems range in scale and scope from simple assists to complete robotic replacements. Inexpensive integrated circuits, sensors and microprocessors have allowed automated systems to become smaller, cheaper and more prevalent. Identifying appropriate opportunities for automation,...

  • Incremental Forming of Polymers at Room Temperature

    Creator:
    Davar Panah, Mohammad Ali
    Abstract:
    Single Point Incremental Forming (SPIF) is a forming process in which a fully clamped sheet is formed by a hemispherical ended tool that moves along a predefined 3D toolpath. The sheet is formed in a series of local deformations to reach its desired shape. Double Sided Incremental Forming (DSIF) includes...

  • Exploring the Effectiveness of Providing Structured Design for the Environment Knowledge during the Conceptual Design Phase

    Creator:
    Ross, Donovan Arie
    Abstract:
    The fuzzy front end of engineering design can present a difficult challenge, and as such, recent engineering design research has focused on guiding and influencing the way a designer ideates. Early ideation can be especially difficult when attempting to integrate specific design objectives in product design, called Design for X...

    Rahrer, Adam P.
    Abstract:
    Over 54 million people report having disabilities in the United States. In addition, there are 40.3 million people 65 years and older living in America. As the population continues to live longer and problems with obesity continue to increase, the number of people with limited capabilities will escalate as well....
