Gaf Glass Mat Splice Table Improvements, Grant Haug, Kevin Lansang, Ronald Lam, Michael Mooney

Mechanical Engineering

The GAF asphalt shingle production line in Shafter, CA requires continuous operation in order to maximize production efficiency. The assembly line process begins with feeding a large roll of fiberglass web into an accumulator. However, once the fiberglass roll approaches the end, it must be spliced with a new roll in order to maintain continuous feed into the production line. The splicing process must be fast and reliable to prevent any delay of the production line. Currently, this process is performed by two workers who manually feed the new fiberglass roll, align the two mats, cut the mats, apply glue …

Development Of A Design Tool For Biologically Inspired Fault Adaptive Design By Strategy Mapping, Nicholas Steven Huisman

Graduate Theses and Dissertations

A design tool for Biologically Inspired Fault Adaption that utilizes the concept of strategy mapping was developed and the development process and testing is presented in this paper. The concept of strategy mapping is derived primarily from the field of military theory and supposes that for any given specific problem, that there exists a specific solution for, a single strategy can be identified for that solution/problem combination. This strategy, when applied to the specific problem yields the specific solution. This specific solution is referred to as the “tactics” of the strategy. The strategy can also be directly applied to a …

Design Of A Meta-Material With Targeted Nonlinear Deformation Response, Zachary Satterfield

All Theses

The M1 Abrams tank contains track pads consist of a high density rubber. This rubber fails prematurely due to heat buildup caused by the hysteretic nature of elastomers. It is therefore desired to replace this elastomer by a meta-material that has equivalent nonlinear deformation characteristics without this primary failure mode. A meta-material is an artificial material in the form of a periodic structure that exhibits behavior that differs from its constitutive material. After a thorough literature review, topology optimization was found as the only method used to design meta-materials. Further investigation determined topology optimization as an infeasible method to design …

Towards A Semantic Knowledge Management Framework For Laminated Composites, Vivek Premkumar

Masters Theses

The engineering of laminated composite structures is a complex task for design engineers and manufacturers, requiring significant management of manufacturing process and materials information. Ontologies are becoming increasingly commonplace for semantically representing knowledge in a formal manner that facilitates sharing of rich information between people and applications. Moreover, ontologies can support first-order logic and reasoning by rule engines that enhance automation. To support the engineering of laminated composite structures, this work developed a novel Semantic LAminated Composites Knowledge management System (SLACKS) that is based on a suite of ontologies for laminated composites materials and design for manufacturing (DFM) and their …

Increasing The Independence Of Children With Spina Bifida Through The Designing And Building Of A Mechanical Aide, Andrew Duffek, Robert Brent, Michael Hamada, Melissa Rodriguez

Industrial and Manufacturing Engineering

In order to assist Silas Hopper, a child with spina bifida, with getting into his wheelchair independently when being on the ground, the senior project team set out to construct a device that would fulfill that purpose. They did this through coming up with a strict definition of the problem to be solved, designing a number of potential solutions for the problem, prototyping to determine the feasibility of the solutions, making design modifications after testing the prototype, and building the final device.

The end product was a device that was able to operate mechanically, with a design that considered safety …

Database Design For The Collection And Visualization Of Sustainabilty Data, Henry A. Kozlowski, Nikhila Perugupalli

Industrial and Manufacturing Engineering

The goal of the project was to create a database that would be a repository for the high volume of sustainability data Illumina would like to collect. To couple with the database the project team’s goal was to design a system for visualizing the data graphically. Illumina required a database system that would be user-friendly, easy to add, delete, and edit data inputs, as well as a program that would allow the user to easily sort and graph data. The intent of the graphical representation of the data is to publish the graphs in a monthly report that would be …

Small Scale Erp Engine Design, Colyn Muir Dickson, Matthew Wade Haymond

Industrial and Manufacturing Engineering

This project set out to create a 1) low-cost, 2) dynamic, and 3) user-friendly small scale ERP software tool. These three key attributes position this product against complex and expensive systems such as SAP or Oracle. While the product still retains the dynamic and financial capabilities any good ERP system should have, the biggest value proposition is its simple and user-friendly interface. The software has a dual product-market fit: for small businesses as a low-cost planning tool, and for universities as a teaching tool. In the design phase, the team kept a primary focus on ergonomic software development while maintaining …

The Design Of An Optimized Patient-Specific In Vivo Spinal Fusion Cage Using Additive Manufacturing, Gorman Donnelly

Honors Theses

This project involved the design of an all-in-one patient-specific lumbar spinal fusion cage using Direct Metal Laser Sintering (DMLS) manufacturing. The cage is zero-profile and does not need the use of supplemental fixation. It was manufactured out of the titanium alloy Ti 6Al-4V using a DMLS rapid prototyping machine from a third party company. The endplates of the cage are patient-specific allowing for a larger surface contact area between the cage and the vertebral bodies than most cages on the market. This fosters a more successful fusion as well as decreases surgery time, effectively decreasing recovery time. Different porosity variations …

Hand Operated Tabletop Letterpress Assembly Instructions 1.0, George Chiu, Brendan Domos, Spencer Herzog, Nathan Sandidge, Kevin Weinstein

Theses

A group of RIT Mechanical Engineering students spent the 2014-2015 academic year in their senior design class collaborating with the RIT Cary Graphic Arts Collection to design and fabricate a 21st century hand-operated platen press.

The press that was designed during this engineering exercise met several requirements:

• be under 30 lbs
• fit in a 24 inch square table top space
• be manufactured with a majority of components which could be purchased from a standard parts supplier
• be able to print with commonly manufactured ink rollers, ink, letterpress chases, spacing and furniture
• the platen and packing had to be adjustable to …

Force Sensing In Arthroscopic Instruments Using Fiber Bragg Gratings, Daniel S. Yurkewich

Electronic Thesis and Dissertation Repository

Minimally-invasive surgery has revolutionized many medical procedures; however, it also impedes the ability to feel the interaction between the surgical tool and the anatomical part being operated on. In order to address this problem, it is necessary to obtain accurate measurements of the interaction forces exerted on the surgical tools during surgery. These forces can then be manifested to the surgeon via a haptic device or presented visually (visual-force feedback). This thesis describes the use of a fiber optic device to measure and display to the surgeon interaction forces acting on an arthroscopic tool. The sensorization of the tool involves …

Designing A Heat Sink For Lithium-Ion Battery Packs In Electric Vehicles, Dylan Irvine, Evan Foreman, Christopher B. Remington, Aaron Jackson, Sam Endrizzi

Williams Honors College, Honors Research Projects

This report addresses the concepts and implementation of fluid cooled heat sink designs for an electric or hybrid vehicle battery. To determine the battery’s temperature and heat flux profile, testing was performed by measuring these values at multiple locations on a lithium-ion pouch battery using heat flux sensors and thermocouples during the charge and discharge cycles of the battery. Once the data was collected and analyzed, trendlines were fit to the heat flux data then used to create equations for the heat flux profile during the discharging stage. Each equation represented a specific region on the battery geometry. Four heat …
