Reducing Soil Compaction In Agriculture, Chris Gum, Justin Manzella, Brett Kayman Aug 2019

Reducing Soil Compaction In Agriculture, Chris Gum, Justin Manzella, Brett Kayman

Washington University / UMSL Mechanical Engineering Design Project JME 4110

Our project was to prototype a device to reduce compaction in soil during industrial agricultural processes. We chose to highlight tilling as the process to focus on, but our final design could be adapted to work for many different applications.


Carbon Fiber Recycler : Fiber Reclaimer, Alexander Edwards Jan 2019

Carbon Fiber Recycler : Fiber Reclaimer, Alexander Edwards

All Undergraduate Projects

Boeing uses composite components for the 777x aircraft. The production of composite parts results in flashing (excess material) that must be trimmed and "thrown away" as scrap. Boeing is investigating means of recycling these scraps. The method proposed for this project is to delaminate and shred the composite material. The delamination process uses a ram to press two claw shaped devices together that bends and deforms the material in opposite directions. The chipper process uses counter rotating saw blades spaced 1/8” apart to produce small shredded material. This shredding material is pyrolyzed (heated) to decay the resin leaving the ...

2019 Up Baja Sae Senior Capstone Project, Jacob Isaacson, Michael Quach, Ryan Hood, Austin Mcnichols

Engineering E-Portfolios and Projects

Baja SAE is an intercollegiate engineering competition where teams design, manufacture and assemble an off-road vehicle that is to serve as a prototype for a recreational user market. The goal of the 2019 UP Baja team was to redesign the existing vehicle into a model that would be eligible to participate in the 2019 Baja SAE competition.

Asme R/C Baja Car, Torrie Large Jan 2018

Asme R/C Baja Car, Torrie Large

Engineering Technology, Safety and Construction Senior Projects

How does one build a car? Do they start with the tires and build inward or do they develop separate aspects at the same time? This remote-controlled car was designed and built with the intention of competing in the annual Baja Competition. There are three competitions: sprinting, slalom, and an obstacle course. The suspension system of this car must be designed to support the car for both the physical build and the competitiveness. It must do this without interfering with the drive train and steering mechanism designed by Doug Erickson. The suspension system employs suspension arms attached to the chassis ...


H.F. Hauff Pruner Cutting Blades, Wyley Stewart Jan 2018

H.F. Hauff Pruner Cutting Blades, Wyley Stewart

Engineering Technology, Safety and Construction Senior Projects

Apple orchards are a critical component of agriculture in the United States, and keeping the apple trees in the best shape for optimum growth and production is hard work. Neil Hauff, an agriculture industry expert, challenged students at CWU to engineer a power assisted tree pruner. Across the country, apple orchards need pruned every season. The pruning of the trees is strenuous manual labor that requires many man hours. The proposed solution is to create a power assisted tree pruner that would minimize the amount of work needed to trim each tree branch. This project has been separated into three ...

Title by Author: Shear Energy by Jason Wittig

Abstract/Artists Statement: Efficiency, function, and weight of fruit-tree pruning devices are scrutinized very closely by the purchasing end user. Efficiency, being the most valuable quality to focus on; an efficient cutting device can lead to smaller batteries and lighter materials on the tree pruner. The objective of this project was to produce a cutting head that surpassed the benchmark device by 10% in four categories: Axial cutting “green-wood,” Axial cutting “dry-wood,” Axial opening force, and Handle twisting torque. The benchmark’s use of the “scissor-type” design was changed to a double ...


Senior Project Hauff Tree Pruner, Brian Woolery Jan 2018

Senior Project Hauff Tree Pruner, Brian Woolery

Engineering Technology, Safety and Construction Senior Projects

Neil Hauff, a business owner and entrepreneur from the Yakima valley challenged a team of engineering students from Central Washington University to design a motorized apple tree pruner. This report will discuss the engineering and construction that went into creating the housing of the tree pruner. The housing component needed to be able to protect the moving parts of the pruner, while withstanding the rotational torque produced by the Makita power drill used to drive the pruner. The biggest constraint in designing the housing was to keep the weight of the housing component under 1.5 lbs, while still keeping ...


Asme Rc Baja Challenge: Suspension And Steering, Hunter W. Jacobson Jan 2018

Asme Rc Baja Challenge: Suspension And Steering, Hunter W. Jacobson

Engineering Technology, Safety and Construction Senior Projects

The American Society of Mechanical Engineers (ASME) usually hosts an RC Baja challenge each year, testing a RC car in three events: slalom, acceleration and Baja. Although ASME will not be holding an event this year, CWU will be holding a similar event with three RC Baja car teams from CWU. The RC car that is tested in these events is designed and manufactured typically in teams of two. The RC car that each team submits must be able to complete these events while also remaining competitive. One part of great importance for the RC car is the suspension and ...

Rc Plane Variable Wing Design, Brian Mincks, Cameron Bard, Noah Rowe Dec 2017

Rc Plane Variable Wing Design, Brian Mincks, Cameron Bard, Noah Rowe

Mechanical Engineering Design Project Class

Each year the AIAA (American Institute of Aeronautics and Astronautics) hosts a design competition where college teams design and fly a small, remote-controlled, battery-powered airplane. For this competition, scoring primarily depends upon the following: maximizing payload, maximizing speed, minimizing weight, minimizing wingspan. Since wingspan is a key scoring factor and variable wing geometry is allowed, our design team has decided to design a pivoting wing system that can be remotely activated immediately before and after takeoff and landing respectively.


The Penn Baxter Face Database, Naomi T. Fitter, Katherine J. Kuchenbecker Mar 2017

The Penn Baxter Face Database, Naomi T. Fitter, Katherine J. Kuchenbecker

Departmental Papers (MEAM)

The Penn Baxter Face Database is composed of Baxter robot face images designed in a variety of expressions and colors. Each of these images was photographed on the physical Baxter robot and assessed by internet raters (N = 568) in an Amazon Mechanical Turk survey. Raters assessed the pleasantness and energeticness of each robot face and also shared how safe and pleased each face made them feel. This project was published in our ICSR 2016 paper entitled “Designing and Assessing Expressive Open-Source Faces for the Baxter Robot.” After hearing of interest from other researchers, we previously released our Baxter face database ...


The Penn Hand-Clapping Motion Dataset, Naomi T. Fitter, Katherine J. Kuchenbecker Nov 2016

The Penn Hand-Clapping Motion Dataset, Naomi T. Fitter, Katherine J. Kuchenbecker

Departmental Papers (MEAM)

The Penn Hand-Clapping Motion Dataset is composed of inertial measurement unit (IMU) recordings from the hand motions of 15 naïve people. Each of these individuals participated in an experiment during which they were asked to pantomime various sequences of 10 different motions: back five, clap, double, down five, front five, lap pat, left five, right five, right snap, and up five. The examined motions comprise most typical actions from hand-clapping games like “Pat-a-cake” and “Slide.” This project was published in our IROS 2016 paper entitled “Using IMU Data to Demonstrate Hand-Clapping Games to a Robot.” After hearing of interest from ...

Active Flow Control Of Low Pressure Turbine Blade Separation Using Plasma Actuators, Karthik Ramakumar Jan 2006

Active Flow Control Of Low Pressure Turbine Blade Separation Using Plasma Actuators, Karthik Ramakumar

University of Kentucky Master's Theses

The current study examines plasma actuators as flow control devices. The actuators are placed on a turbine blade profile in a 2D turbine cascade for separation flow control. The configuration involves copper strips separated by a layer of dielectric material, across which an AC electric potential in the range of 5 kHz and 5 kV is applied. The efficiency of the actuator is monitored by measuring power input and flow control effectiveness. Preliminary observations are performed for a quiescent case on a flat plate profile to analyze the average and instantaneous velocities generated by the actuator for varied input parameters ...
