Inverted Pendulum With Swing-Up And Center-Stabilization System Design, Caleb Osmond
Inverted Pendulum With Swing-Up And Center-Stabilization System Design, Caleb Osmond
Honors Theses
The inverted pendulum is a classic problem for testing control techniques. This paper details the implementation of multiple PID control schemes and the overall design of an inverted pendulum capable of swing-up and center stabilization.
Husker Motorsports Active Drag Reduction System, Creighton Hughes, Evan Killian, Micah Busboom, Aj Johnson, Jude Steffen
Husker Motorsports Active Drag Reduction System, Creighton Hughes, Evan Killian, Micah Busboom, Aj Johnson, Jude Steffen
Honors Theses
Formula SAE is a multifaceted competition that involves student teams designing and competing with an open-wheel style race car. There are 5 different dynamic events included in the competition. Each event requires a unique aerodynamic setup to have the best performance possible. This design project focuses on a drag reduction system (DRS) that will improve aerodynamic performance, resulting in faster lap times and increased competitiveness. Key features include a direct electronic actuation mechanism that will allow the rear wing to be adjusted during a race. The benefits of the DRS system, include increased speed, improved handling, and greater fuel efficiency …
Stump Grinder Project, Wyatt Hopper
Stump Grinder Project, Wyatt Hopper
Honors Theses
This project covers the analysis of a Portable Stump Grinder device sponsored by private investors known as Gary and Carol Sherman, two farmers out of Lincoln, Nebraska. The ultimate goal of this project, in terms of the work we were assigned, was to provide the foundation work for future engineering teams to design and build the stump grinder for Gary and Carol Sherman.
Leadership And Project Management In Engineering: Baja Tube Bender, Maysyn Tm Sorensen
Leadership And Project Management In Engineering: Baja Tube Bender, Maysyn Tm Sorensen
Honors Theses
Typical coursework for Undergraduate Mechanical Engineering students does not deeply focus on project management and leadership. Detailed in the following documentation is review of my Mechanical Engineering Senior Design capstone project as well as analysis of final presentations of other capstone projects. The Senior Design capstone projects spanned both semesters of the ‘22-’23 academic school year. After the first semester of my project I produced a post-mortem report to analyze the project’s progress and suggest improvements for the project, design, and team interaction. These improvements were compiled into an action plan and implemented in the spring semester. When the project …

The Effect Of Store-To-Store Energy Transfers On The Global Dynamics Of Aircraft, Guilherme Mainieri Eymael
The Effect Of Store-To-Store Energy Transfers On The Global Dynamics Of Aircraft, Guilherme Mainieri Eymael
Honors Theses
This study analyzes the energy transfer mechanisms when nonlinear devices (stores) are attached to a linear model airplane. For that, a reduced-order model (ROM) was derived to simulate the first two flexible modes of vibration of the primary structure (aircraft) with one store in each wing. Each store can either be locked or unlocked. When locked, it only contributes as mass-effect, and when unlocked, it adds nonlinearity to the system. Simulations were then performed with either both stores locked, one store unlocked, or both stores unlocked. It was found that the attachment of nonlinear stores in the ROM changes the …
Development Of Controller Area Network Bus Programming For Quarter-Scale Tractor Pulling Sled, Brittani Wacker
Development Of Controller Area Network Bus Programming For Quarter-Scale Tractor Pulling Sled, Brittani Wacker
Honors Theses
Usage of Controller Area Network (CAN) technology has allowed for advancements in many industries, including agriculture. Most importantly, its application is useful for refining data acquisition methods. With support from the Quarter-scale Tractor Design Team at UNL, this project united a CAN bus with the team’s current tractor pulling sled. The objectives were to install new instrumentation needed for the CAN bus and to program the updated system utilizing CAN data. The program needed to give the pulling sled functionality and the ability to read and log important pulling data. These goals were all accomplished by implementing new sensors, coding …
A Review On Heat Flux Measurement Techniques In The Nano And Microscale, Miguel Moreno
A Review On Heat Flux Measurement Techniques In The Nano And Microscale, Miguel Moreno
Honors Theses
Heat Flux measurements represent an important step in obtaining an accurate heat transfer profile in many engineering problems. Sensors capable of measuring this quantity have been around for decades, however, the increasing focus in nano and microscale applications in the industry and academia demands more accurate and smaller devices. This paper reviews some of the methods used to develop heat flux meters targeted to nano and microscale, as well as some calibration processes for the same. A combination of Luminescence and non-luminescence methods for direct and indirect measurement of heat flux will be discussed. A glimpse of what the future …
Geometric Iteration Of A Knee Prosthetic And Static Stress-Bearing Capacity, Alexander Wheeler
Geometric Iteration Of A Knee Prosthetic And Static Stress-Bearing Capacity, Alexander Wheeler
Honors Theses
The purpose of this study was to improve a prosthetic knee model in terms of size, weight, and biocompatibility. Several tests were run to determine its effectiveness in supporting static and quasistatic loads. The positions in which these tests were run include static upright standing, static one-knee 90 degree kneeling, static squatting at maximum flexion, and quasistatic midstride. These simulations were conducted to find areas of high stress and strain. These patterns were used to determine the maximum body weight a physical prosthetic could support. The material used to create the prosthetic was changed from AISI 316 stainless steel to …
The Business Case For Industrial Safety: Revealing The Comprehensive Value Of Ergonomic Investments For Manufacturing Enterprises In Industry 4.0, Shane Stan
Honors Theses
How can today’s manufacturing enterprises construct, implement, and optimize modern safety initiatives in a manner that will present maximum return on investment and facilitate enterprise growth? Furthermore, how can these manufacturers assure individual ergonomic investments become part of a larger strategy to facilitate organizational change in safety? This work addresses these questions by placing industrial ergonomics in a business improvement context which comprehensively presents the financial returns and growth opportunities poised by modern safety initiatives. Additionally, to further strengthen the business case for industrial safety, an ergonomic action planning framework is established to guide the creation of holistic safety programs …
Using The Soar Approach To Teach Middle School Students About Math And Science Concepts Found In Engineering, Rachael Wagner
Using The Soar Approach To Teach Middle School Students About Math And Science Concepts Found In Engineering, Rachael Wagner
Honors Theses
In order to address the lack of knowledge about the engineering profession in middle-level students, the project described in this Honors Thesis was developed. Through the creation of an afterschool program centered on engineering, students were able to apply the math and science concepts covered to design, build, and test a bridge. One particular lesson from this after-school program was highlighted in this thesis, the lesson covering the Pythagorean Theorem, to demonstrate the use of SOAR methodology in the lesson’s development and later use in the classroom. The effectiveness of the Pythagorean Theorem lesson was evaluated positively based on the …
