Electromagnetic Actuator For Camless Engines, Nicholas Olesh, Charlie Thomas Glenwright, Tim Wills De Tone, Darya Daniel Darvish
Mechanical Engineering
This document summarizes the research, objectives, project plan, and design for developing an electromagnetic actuator valve for use in a camless internal combustion engine. While electromagnetic valve actuators have not been implemented into a working product to date, there have been many attempts to research and develop working prototypes. Similar products have been developed, but they do not use purely electromagnetic actuation. This research is significant because it shows the challenge that must be overcome and outlines potential design solutions to the problem. The objectives section highlights the problem statement and what is aimed to be achieved in this project. …

Mechanical Engineering
The purpose of the Heavenly Bodies RSVP project was to design and fabricate planet props, as well as a mechanism by which they could be raised and lowered in California Polytechnic State University’s Pavilion theater. The project team was comprised of four fourth year mechanical engineering students: Allison Turnbaugh, Braden Lockwood, Jack Boulware, and Justin Spitzer. We conducted extensive research to determine the ideal solution for the design problem brought to us by our sponsor. In our analysis, we discovered that the most important aspects of our design were the absolute reliability of the system, fire retardant material selection, and …

Improvements need to be made to the existing delaminator system designed to crush proprietary Boeing 777 composite material. The current design incorporates a hydraulic system to achieve the high loads needed to separate material layers. The new system will need to be able to apply the same loads while at the same time allowing for a constant feed of material through the system. To achieve this, a “gear-like” crushing system will be implemented that will apply a high enough radial load into the material that will achieve delamination equal or greater than the previous design while at the same time …

This thesis work introduces a novel multi-fidelity modeling framework, which is designed to address the practical challenges encountered in Aerospace vehicle design when 1) multiple low-fidelity models exist, 2) each low-fidelity model may only be correlated with the high-fidelity model in part of the design domain, and 3) models may contain noise or uncertainty. The proposed approach approximates a high-fidelity model by consolidating multiple low-fidelity models using the localized Galerkin formulation. Also, two adaptive sampling methods are developed to efficiently construct an accurate model. The first acquisition formulation, expected effectiveness, searches for the global optimum and is useful for modeling …

Williams Honors College, Honors Research Projects
This project is focused on the design of a new and innovative lacrosse stick. Our main points of focus will be the strength and durability of the head. As well as solving some of the problems that exist in existing equipment. These problems were identified by interviewing experienced players at the college level. Benefits would include a stronger head that is easier to use for a player on the field to do things like pass, catch, shoot, and field ground balls in an optimal manner. Normally players will have to purchase new heads every season as a result of warping …
Mini Baja Frame Analysis, Jacob Swanson
Mini Baja Frame Analysis, Jacob Swanson
Williams Honors College, Honors Research Projects
The purpose of our senior design project is to optimize the Baja frame to reduce its weight and material cost while keeping the required rigidity. Through force analysis we will be able to determine if any rigidity is lost by removing a set of tubes (figure 1), along with the other forces seen by the frame. If it is found that the frame rigidity is still within the determined factor of safety, 2, then we will be able to reduce the frame weight and the number of tubes that make up the frame. Along with force analysis, we will use …

The need for hands-on and face-to-face experiences in the engineering classroom is very great. The equations, principles, and concepts can all be learned, but without the visual and tactile application, these don’t always sink in or become concrete. A small-scale tensile test machine was designed, sourced, manufactured, and tested for the purpose of being applied in classroom settings to provide this experience to engineering students. Extensive research was performed concerning tensile machines on the market, the essential elements of which are the load cell, grips, crosshead, extensometer, motor, and frame. The raw materials for the frame were purchased and drawings …
