Exploring experimental test stand design and operation within a system reliability research methodology

Creator:: Koopmans, Michael, 1986-
Abstract:: In cases where complex systems routinely experience extreme operating conditions, preventative maintenance is often employed to guard against system failure. Yet, with accessible real-time data and the standard practice becoming prohibitively expensive, the test stand can serve as a vital contributor to the development of system health and reliability estimations....

Numerical and Experimental Investigation of Wing Flutter Suppression via Distributed Propulsion

Creator:: Anderson, Cole J.
Abstract:: In a seminal paper published in 1982, scientist have warned that humanity was pushing earth’s ecosystems beyond their capacities to support the web of life. One response to the concern was outlined by NASA with its vision for advanced fixed wing transport aircraft to be environmentally compatible and have revolutionary...

Automated Tradeoff Analysis of Cost Versus Machinability for Design Feedback

Creator:: Grier, Alan Thomas
Abstract:: As CAD tools become more sophisticated, engineers are able to more easily create complex part geometries with minimal mass given strength and stiffness requirements. However, these complex part geometries can be difficult to subtractively manufacture, which consequently increases manufacturing cost and production time. This thesis presents a method independent of...

Study of the Effects of Chain Whip Length and Bar Length on the Characteristics of Chain Shot

Creator:: Shannon, Eric R.
Abstract:: Timber harvesters are high powered industrial grade rigs used to fell, delimb, and cut to size large trees. Hydraulic motors power sprockets that drive chains around a guide bar that get extended through logs during cuts. As technological advances allow for higher speeds a phenomenon called “chain shot” has...

Floating Offshore Wind Array Systems Optimization off the US West Coast using an Extended Pattern Search Algorithm

Creator:: Forinash, Caitlin P.
Abstract:: The large wind resource off the United States West Coast has the potential to generate wind power for millions of homes, yet the high cost of energy for offshore wind power compared to traditional sources has slowed the development of offshore wind farms in the US. The four studies presented...

Properties of veneer sliced from serpentine-end-matched flitches

Creator:: Liu, Yuqing
Abstract:: Eighteen Ponderosa Pine (Pinus ponderosa Dougl.ex.laws) veneer flitches were randomly selected and crosscut into paired flitches. Serpentine-end-matched (SEM) joints were machined in the flitches, joint amplitude equal to the width in one half of the paired flitch and joint amplitude equal to 2/3 width in the other half of the...

Design, modeling, and performance of miniature reciprocating thermocompressor

Creator:: Edwards, Michael J.
Abstract:: Research in the miniaturization of thermomechanical systems in recent years has proven to be both rewarding and challenging. Micro-scale devices have tremendous technological potential but come with a new set of design problems. One such problem is energy storage. Heat actuated systems, driven primarily by thermal energy, take advantage of...

Adaptive methods for robust commercial vehicle control

Creator:: Junell, Jaime L.
Abstract:: This thesis explores the implementation of learning based control with predictive cruise control and the potential this technology has for increasing fuel efficiency while keeping on a well maintained schedule for commercial trucks. Traditional cruise control is wasteful when maintaining a constant velocity over rolling hills. Predictive cruise control is...

Design analysis using function-based failure propagation in failed system states

Creator:: Jensen, David Charles
Abstract:: For safety critical complex systems, reliability and risk analysis are important design steps. Implementing these analyzes early in the design stage can reduce costs associated with redesign and provide important information on design viability. In the past several years, various research methods have been presented in the design community to...

Comparing and Contrasting the Merits of Additive Manufactured Electric Vehicle Suspension Components: GFR Case Study

Creator:: Peraza-Garcia, Jesus
Abstract:: This thesis compares the implementation of additive manufactured suspension uprights against subtractive manufactured suspension uprights from concept generation, design, and validation through simulation. Additive manufactured suspension uprights were designed for Global Formula Racing’s 2023 electric vehicle. Utilizing Siemens NX, Nastran, Fusion 360, and Ansys Workbench both subtractive and additive manufactured...
