Reinventing The Wheel, Esther K. Unti, Ahmed Z. Shorab, Patrick B. Kragen, Adam M. Menashe Dec 2018

Reinventing The Wheel, Esther K. Unti, Ahmed Z. Shorab, Patrick B. Kragen, Adam M. Menashe

Mechanical Engineering

Reinventing the Wheel selected tires and designed wheels for the 2018 Cal Poly, San Luis Obispo Formula SAE combustion vehicle. Available tire options were evaluated for steady-state and transient performance as well as vehicle integration. A single-piece composite wheel with hollow spokes was designed to meet stiffness, strength, and tolerance requirements. A detailed study of wheel loading and geometric structural efficiency was performed. Finite element analysis was used to iterate the geometry and laminate. A two-piece male mold was designed and machined to manufacture the wheel. Removable silicone inserts were used to create the hollow spokes.

Advances In Automotive Conversion Coatings During Pretreatment Of The Body Structure: A Review, Mark Doerre, Larry Hibbitts, Gabriela Patrick, Nelson K. Akafuah

Automotive conversion coatings consist of layers of materials that are chemically applied to the body structures of vehicles before painting to improve corrosion protection and paint adhesion. These coatings are a consequence of surface-based chemical reactions and are sandwiched between paint layers and the base metal; the chemical reactions involved distinctly classify conversion coatings from other coating technologies. Although the tri-cationic conversion coating bath chemistry that was developed around the end of the 20th century remains persistent, environmental, health, and cost issues favor a new generation of greener methods and materials such as zirconium. Environmental forces driving lightweight material selection ...

Mechanical Characterization And Shear Test Comparison For Continuous-Fiber Polymer Composites, Matthew Crossan Apr 2018

Mechanical Characterization And Shear Test Comparison For Continuous-Fiber Polymer Composites, Matthew Crossan

Electronic Thesis and Dissertation Repository

As fiber-reinforced composites continue to be used in a wide-range of high performance structures, more detailed understanding and accurate prediction of stress-strain behaviour is necessary to improving designs and reducing costs. This thesis compares the experimental behaviour of a continuous fiber polymer composite of carbon fiber and epoxy resin using Digital Image Correlation to analytical and theoretical predictions. Furthermore, an in-depth analysis of shear testing methods reveals the advantages and limitations of different testing standards. Finally, the limitations of the Iosipescu Shear test (ASTM 5379) fixture to break high-strain-to-failure composites in comparison to the V-notched Rail Shear Fixture (ASTM 7078 ...


A Laboratory Kit For Multimeter Design, Seth Percy, Joshua Perry Apr 2018

A Laboratory Kit For Multimeter Design, Seth Percy, Joshua Perry

Thinking Matters Symposium

The multimeter is an important electrical tool and is a combination of many individual instruments. In practice, common multimeter designs are digital and measure voltage, current, resistance, capacitance, etc., using a single set of probes. Before the digital age, the world relied on analog displays. Some argue that analog displays are outdated technology. However, this overlooks one of the most important characteristics provided by the analog display, which is its ability to provide an instantaneous visual perception. Analog displays are currently used for many applications in aviation and automobiles, demonstrating their continuing usefulness in the field. In the multimeter, the ...


Manufacturing A Composite Wheel Prototype Using 3d Printed Molds, Steven Thuening Jan 2018

Manufacturing A Composite Wheel Prototype Using 3d Printed Molds, Steven Thuening

All Theses, Dissertations, and Other Capstone Projects

Throughout the evolution of high performance racing, a large emphasis has been on reducing the weight of the vehicle in order to improve its performance. Over the years, new designs and materials have been introduced reducing weight in a variety of different locations. Comparing weight reduced in different areas has shown that some areas are more valuable to reduce than others are. Perhaps one of the most beneficial locations are the wheels. This is because the mass of the wheel is considered unsprung and rotational. Because of this, large improvements towards the reduction of wheel mass have been developed in ...
