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 …

Carbon Articulating Backpack Spine, Salvatore Monforte Iii, Darci Lawrence, Savan Patel

Mechanical Engineering

In the field, firefighters and Urban Search and Rescue (USAR) personnel need to transport variable loads efficiently, safely, and comfortably while simultaneously performing certain physical tasks. Current models of external and internal framed backpacks distribute the load of a pack efficiently, but do not allow for the natural movement of the wearer. Wolfpack Gear, Inc. proposed the need for a system which both effectively carries a load and allows for the unhindered natural movement of the user. The goal of this project was to design, build, and test an articulating backpack support system. The first stage of the project comprised …

PolySat is a student-run, Cal Poly research program in which students develop small satellites, known as CubeSats, to be sent into space. Since the start of the program in 2000, PolySat has developed eight 10cm x 10cm x10cm CubeSats. Recently, the team has developed two satellites of double, and triple, that size for NASA-KSC & AI-Solutions and the National Science Foundation. The recent volumetric expansion has been driven by high demand for further satellite functionality, which necessitates large power generation capabilities. To remain competitive in the growing CubeSat industry, PolySat must develop a platform that can provide enough power to …

Freedom Ski, Toby A. Goldsteinholm, Ashley Scharff, Justin Satnick, Markus Rutner

Mechanical Engineering

The current availability of water skis for people who are paraplegic or quadriplegic is very limited. The aim of our project is to design a system that improves upon the current models of specialized water skis. Our intent is to create a waterski system that is structurally stable and handles responsively, in order to ensure that anyone is capable of effectively using our system to waterski.

The main client of our project is Quality of Life Plus, an organization that aims to aid veterans of the armed forces who have physical disabilities to still enjoy a good quality of life. …

Deltronic Solutions Delta 3d Printer, Ramon Santos, Justin James, Taylor Chris, Stephen Marshall, Paul Maalouf

Mechanical Engineering

The Delta 3D Printer project is a 2014-2015 Cal Poly ME senior project sponsored by Dr. Jose Macedo, Professor and Department Chair of the Cal Poly IME Department; Yaskawa America, Inc., industry-leading producer of high-quality electronic drives and motors; and Bell-Everman, Inc., producer of high-precision embedded motion systems. The Delta 3D Printer project was conceived by Dr. Macedo as a collaboration between Cal Poly engineering and Yaskawa America. The majority of delta 3d printers on the market utilize stepper motors to control the print head motion. The 3D printer for this project was designed to use servo motors instead of …

Human Powered Vehicle Frame Design, Matthew S. Allen, Peter B. Aumann, Trent J. Hellmann

Mechanical Engineering

This report discusses the Human Powered Vehicle Frame Design senior project’s contributions to the design, manufacture, testing, and competition of the Cal Poly Human Powered Vehicle Club’s 2015 vehicle, Sweet Phoenix. The project’s guiding rules and timeline were dictated by the ASME Human Powered Vehicle Challenge (HPVC), held in April 2015. The Club sought to improve upon its previous vehicle, Aria, which suffered from a range of faults including a catastrophic structural failure at the 2014 HPVC. Largely in response to this failure, the Frame Design project’s major focus was Sweet Phoenix’s frame, from concept to manufacturing. During the design …

Parker Hannifin Chainless Challenge 2014-15 Senior Design Project, Matt Pallotta, Nathan Klammer, Kemper Whaley, Jack Rechtin

Mechanical Engineering

California Polytechnic State University has been invited to compete in the Parker Hannifin Chainless Challenge Competition in 2014-15. Cal Poly has chosen a team of mechanical engineering students to take part. We have named our team “Bike Under Pressure” and all references as such refer to the team.

The challenge is to build a bicycle which does not have a solid mechanical connection between the power input of the rider to the power output of the wheel(s). After conducting research into different previous designs and brainstorming designs of their own, Bike Under Pressure developed two conceptual designs. One design featured …
