The world is currently using an unsustainable system of meeting its transportation
needs with oil. This system is taking a toll on the world environment and on global politics.
The physical availability of oil is the system’s most immediate problem and will most likely
bring about a transition away from...
Ocean Wave Energy Converters (WECs) operating on the water surface are subject to storms and other extreme events. In particular, high and steep waves, especially breaking waves, are likely the most dangerous to WECs. A method for quantifying the breaking severity of waves is presented and applied to wave data...
Aerodynamic improvements in automotive racing can have a significant effect
on vehicle performance. Recent developments in Formula SAE (Society of
Automotive Engineers) have included the design and implementation of aerodynamic
devices such as inverted wings and undertrays to improve performance. In this work
the literature of undertray technology is presented...
Customer requirements and engineering specifications will influence the direction of the design in any product, so it is crucial to make the requirements as stable as possible so quality designs can be produced on time within a budget. It would be optimal for requirements and specifications to remain constant but...
Wave energy conversion is still in its infancy, and in order for it to become a commercially viable technology, developers, investors and utilities need to estimate a Wave Energy Converter's (WEC's) performance for the wave climate of a potential installation site. With the goal of estimating a design's power output...
Future engineers need to be competitive in today's expanding global industries. They must have capabilities beyond standard engineering practice. In an attempt to develop students capable of working in a globally distributed design and manufacturing environment, Oregon State University (OSU) and Duale Hochschule Baden-Württemberg Ravensburg (DHBW) have developed a senior...
This thesis investigates the applicability of the finite element method to model wave energy converter (WEC) hydroelasticity using LS-DYNA. The proposed methodology uses the Arbitrary Lagrangian-Eulerian formulation to model Fluid-Structure Interaction (FSI) between the WEC and the fluid elements. This formulation allows for time-domain modeling of higher order effects such...
In this dissertation, a group of vehicle dynamics simulation tools is developed with two primary goals: to accurately represent vehicle behavior and to provide insight that improves the understanding of vehicle performance. Three tools are developed that focus on tire modeling, vehicle modeling and lap time simulation.
Tire modeling is...
A student-built lap time simulation coupled with the scoring model of the Formula Society of Automotive Engineers (SAE) Series has revealed the major importance of downforce on overall points. As a result, the Global Formula Racing (GFR) team has recently focused much effort towards the development of an aerodynamics package...
Hydraulic power take-off (PTO) systems have been implemented in several wave energy converter (WEC) designs in recent years. Two popular hydraulic PTO configurations coupled to a point absorber hydrodynamic model are simulated in waves representative of an energetic sea state likely to be found in deep waters off the coast...
