Mechanical Design And Optimization Of An Interactive Animatronic Bald Eagle, Eric Burns

Phi Kappa Phi Research Symposium (2012-2016)

Animatronics is a specialized sub-category of mechatronics, a fusion of mechanical and electrical engineering. The field has grown from small, individual projects into a major industry. As animatronics progress, mechanical engineers are pushed to design internal structures which occupy ever-decreasing spaces and to ensure designs can undergo maintenance and modifications smoothly. This research investigates methods of reducing space required for mechanisms and several other beneficial methods of development as well as varying satisfactions for audiences when exposed to actor-controlled systems rather than pre-scripted functions. The mechanical systems are designed using CAD software available at Georgia Southern. On-campus, resources are used …

Dynamic Simulation And Analysis Of Fsae Racer For Development Of Stability Control System, Stone D. Williford

Honors College Theses

Using Adams/Car software, a computer model of Georgia Southern University’s 2016 Formula Society of Automotive Engineers (FSAE) racecar was developed with the purpose of researching vehicle stability under dynamic conditions. Previous research in this field of study has been conducted to verify that Adams/Car simulations provide accurate results using data acquisition systems, so the major work for the current research has been to create an updated version of the vehicle designed and fabricated by Eagle Motor Sports. With this new model, vehicle roll, and pitch data as well as vehicle traction were collected during dynamic simulations. The overall goal for …

Wire + Arc Additive Manufacturing, Micheal Santangelo

GS4 Georgia Southern Student Scholars Symposium

Additive manufacturing is a rapidly developing technology which promises to drastically reduce the cost and waste associated with manufacturing parts. However, current systems of additive manufacturing used for creating metal parts which are suitable for use in the aerospace, automotive, and defense industries are complex, expensive, and not robust enough to produce a wide range of part features and geometries. A relatively new method, called wire arc additive manufacturing(WAAM) is a low cost option that can create parts which have a near-net shape, and only require a small amount of post processing before they are ready for use. This system, …

Fabrication Of Nano-Scale Metal Organic Framework (Mof) Loaded Nanofibrous Membrane For Enhanced Gas Adsorption Performance, Wahiduz Zaman

GS4 Georgia Southern Student Scholars Symposium

Nitrogen storage capacity was investigated on a highly efficient adsorbent nanoparticle called Metal Organic Framework (MOF). A copper-based MOF called MOF-199 has been synthesized from subsequent reaction of Copper nitrate (10 wt.%), Trimesic Acid (8 wt.%) and Triethylamine (0.3 wt.%). TEA served as a deprotonating agent to form small particles. The reactants were mixed in a solution of Dimethylformamide (DMF), Ethanol and Deionized water (1:1:1) and vigorously sonicated for an hour at room temperature. This yielded single blue octahedral MOF crystals which were later washed with mother solution and extracted via centrifuge. The MOFªs were later activated for gas adsorption …

Scalability Of Microscale Fractal-Like Branching Channel Networks, James R. Miller Iii

Honors College Theses

Fractal-like branching channel networks have been shown to offer the advantages of reduced pumping power and lower maximum wall temperatures when employed in the design of microscale heat sinks. Unfortunately, previous literature has been limited to microscale flow networks. In this paper, a microscale flow network will be scaled up to result in a mesoscale flow network and a macroscale flow network. In order to compare the pressure drop across the flow networks of varying scales the results will be nondimensionalized in the form of the Euler number. For a laminar inlet Reynolds number the microscale, mesoscale, and macroscale fractal-like …

Experimental And Numerical Investigation Of Aerodynamic Performance For Vertical-Axis Wind Turbine Models With Various Blade Designs, Travis E. Salyers

Electronic Theses and Dissertations

The demand for wind energy as a renewable source is rising substantially. A growing interest exists in utilizing potential energy conversion applications in areas with less powerful and less consistent wind conditions. In these areas, vertical-axis wind turbines (VAWTs) possess several advantages over the conventional horizontal-axis type. Savonius turbines are drag-based rotors which operate due to a pressure difference between the advancing and retreating blades. These turbines are simpler in design, less expensive to install, non-dependent of wind direction, and more efficient in lower wind speeds. In the present study, six different rotor designs with equal swept areas are analyzed …

Aerodynamic And Modal Analyses Of Small Scale Horizontal Axis Wind Turbine With Various Numbers Of Blade Design, Emile Maroha

Electronic Theses and Dissertations

With the global energy demand rising to unprecedented numbers, the need for alternative energy sources is ever prevalent. Wind energy is the most alternative renewable sources today due to its year-round availability and pollution-free nature. Horizontal Axis Wind Turbines (HAWT) are the most popular because of their higher efficiency. The aerodynamic characteristics and vibration of small scale HAWT with various numbers of blade design have been investigated in this numerical study in order to improve its performance. SolidWorks was used for designing CAD models, and ANSYS software was used to study the dynamic flow around the turbine as well as …

Enhancing Project Management With Lean World Class Manufacturing In Construction, Jacob Randles

Electronic Theses and Dissertations

In construction, the goal of commercial projects is to turn a profit. This is achieved by minimizing inputs and maximizing outputs while building a product that meets the customer’s perception of value. Value is determined through pre-negotiated specifications, plans, and material quality. Even in U.S. military construction, the unit executing the construction wants to complete the task on time and on budget, which can be difficult to do. Studies on project completion showcase a surprisingly high rate of failure in reaching the aforementioned “on time, on budget” goal. It is important to understand the nuances and details of U.S. Army …
