Efficiency Analysis Of Harvesting Solar Energy To Perform Mechanical Work, Haden S. Bragg
Efficiency Analysis Of Harvesting Solar Energy To Perform Mechanical Work, Haden S. Bragg
Undergraduate Theses and Capstone Projects
The majority of the world’s electricity is generated using fossil fuels; in fact, the United States Energy Information Administration (EIA) states that the U.S. used fossil fuels to generate 62.7 % of its electricity in 2019 [1]. The goal of this research was to create a system that could perform mechanical work using only renewable resources. We built a solar charging station that uses two solar panels to generate electricity and an electric bicycle whose battery can be charged using the charging station. The efficiency for the type of solar cell used in this project is well established. Therefore, in …
Transportation Analysis And Related Design Optimization Of The Fermilab High-Beta 650 Mhz Cryomodule, Josh F. Helsper
Transportation Analysis And Related Design Optimization Of The Fermilab High-Beta 650 Mhz Cryomodule, Josh F. Helsper
Graduate Research Theses & Dissertations
The Proton Improvement Plan-II (PIP-II) at Fermi National Accelerator Laboratory(FNAL) will create a new and vastly improved accelerator, which will be the source of high energy particles for the experiments taking place at FNAL. The new linear accelerator (LINAC) contains several types of cryomodules, which are individual particle accelerators. The last cryomodule in the LINAC will be the High-Beta 650 (HB650), which will operate at 650 MHz. Each module is approximately 15 meters in length, 1.5 meters wide, weighs 13 tonnes, and shares many design features with three of the other cryomodules. The HB650 consists of two primary sections, the …

Might-E Wheel, Abigail Grills, Daniel Doke, Jared O'Rourke, Zach Jesberger
Interdisciplinary Design Senior Theses
Electric bikes are proving to be an increasingly reliable source of transportation, but with large price tags and existing conversion kits proving too complicated and unapproachable for the average user, commuters are failing to consider electric bicycles as an option. A prototype of a wireless, rear-wheel replacement to convert a bicycle from manual to full-power electric was built. This motorized wheel is called Might-E Wheel. Might-E Wheel was designed as the most approachable and user-friendly way to convert a bicycle from manual to full-power electric. Might-E Wheel was able to achieve a top speed of 27.5 km/h, a range of …
Bikeshare Business Model For Cal Poly- San Luis Obispo, Justin Benson, Andrew Neil Gatchalian
Bikeshare Business Model For Cal Poly- San Luis Obispo, Justin Benson, Andrew Neil Gatchalian
Industrial and Manufacturing Engineering
With the increasing admittance of students into colleges and universities across the nation, the need for alternate modes of transportation is becoming more pressing. College and university campuses, as well as small cities, in which there is a college or university, are being overloaded with student cars. In San Luis Obispo specifically, parking on campus as well as downtown can be extremely difficult to find. Traffic is also getting progressively worse, especially at the hour when class begins/ends and student arrive to or leave campus. Financial reasons are yet another deterrent for students at Cal Poly. Parking permits, gas, and …
Design And Testing Of An Automated Semiâ]Trailer Control System, Conor H. Dodd
Design And Testing Of An Automated Semiâ]Trailer Control System, Conor H. Dodd
Honors Theses
Growing up in Maine, the trucking industry is an ever-present part of life. With a very sparse, lightly used rail system, almost all of the raw materials and goods that enter and leave the state do so by truck. Truckers in Maine are constantly challenged by Maine’s roads, which can often be difficult or even treacherous to navigate. The rough logging roads near Jackman or Millinocket, or the sharp ninety degree turns near the Portland oil docks, can ruin a trucker’s day, or even worse, cause an accident. For example, there is a tiny four-way intersection on Broadway in South …
Design And Development Of Rapid Battery Exchange Systems For Electric Vehicles To Be Used As Efficient Student Transportation, Jonathan A. Bevier
Design And Development Of Rapid Battery Exchange Systems For Electric Vehicles To Be Used As Efficient Student Transportation, Jonathan A. Bevier
Master's Theses
Rapid battery exchange systems were built for an electric van and pedal assist electric bike as a method of eliminating the need to recharge the vehicles batteries in order to increase the feasibility of using electric propulsion as a method of efficient student transportation. After selecting proper materials it was found that the systems would need a protective coating to ensure consistent operation. 1020 cold rolled steel samples coated with multiple thicknesses of vinyl resin paint, epoxy resin paint, and powder coating were subjected to environmental wear tests in order to determine if the type and thickness of common protective …
Robustness And Control Of A Magnetically Levitated Transportation System, Grzegorz Oleszczuk
Robustness And Control Of A Magnetically Levitated Transportation System, Grzegorz Oleszczuk
Mechanical & Aerospace Engineering Theses & Dissertations
Electromagnetic suspension of Magnetic Levitation Vehicles (Maglev) has been studied for many years as an alternative to wheel-on rail transportation systems. In this work, design and implementation of control systems for a Maglev laboratory experiment and a Maglev vehicle under development at Old Dominion University are described. Both plants are modeled and simulated with consideration of issues associated with system non-linearity, structural flexibility and electromagnetic force modeling. Discussion concerning different control strategies, namely centralized and decentralized approaches are compared and contrasted in this work. Different types of electromagnetic non-linearities are considered and described to establish a convenient method for modeling …
