2 Degree Of Freedom Robotic Leg, Oded Tzori, Henry Terrell, Adan Martinez

Mechanical Engineering

Professor Xing, an assistant professor at Cal Poly, proposed the 2 DOF Robotic Leg project for this quarter’s senior project class. The project is to build a robotic leg attached at the hip to a stand, which will be used as a teaching tool and eventually help develop Cal Poly’s very own robotic quadruped. Since this project has multiple uses after its completion, there are multiple customers that it must perform well for: the Cal Poly Mechanical Engineering (ME) Department, the ME Lab instructors, and the students. The Scope of Work (Sections 2 & 3) is composed of 2 main …

Cp Check Valve Design, Alec B. Der Matoian, Jessica M. Dent, Skylar M. Tusting

Mechanical Engineering

This report is to serve as a final design review and update to the project sponsors at Zurn Wilkins for the Check Valve Design Senior Project. The senior project team was tasked with improving upon the design of Zurn Wilkins’ backflow prevention assembly for small diameter pipes by reducing the pressure loss created by the check valves within the double check backflow assembly. The information contained in this report builds off the information contained in the Critical Design Report (CDR), as well as feedback and further investigation suggested during an Intermediary Design Review. Based on conclusions from the CDR, our …

Design Of An Orientation Device For Valve Bodies With Blowout Compatibility For Slug Detection, Annie Richardson

Honors Theses

The Parker Hannifin plant in Batesville, MS, is a manufacturing plant that specializes in A/C and hydraulic tube and hose assemblies that support heavy machinery in the agriculture, logistics and construction industries. Customers place unique orders where the tube size, bending configurations, and adaptors vary widely. Some tubes require valve bodies where the customer can charge the A/C system once it has been assembled. A pierce and press machine is used to pierce the tube and place the valve body in the hole. Many tubes have asymmetric blocks at the end of the tube, with valve bodies placed at customer-requested …

A Study Of The Design And Manufacturing Of An Elevated Dog Feeder, Lena Turner

Honors Theses

ABSTRACT

The senior capstone which students in the Center for Manufacturing Excellence program partake in was the basis for project. The Dog Box is an elevated dog feeder with an internal food storage compartment. It was designed for medium to large dogs, and can hold over 40 lbs of dog food. The internal storage compartment has drawer access and contains a plastic tote that will hold the food. The purpose of the design was to create an aesthetically pleasing elevated dog feeder that would double as a storage device, and elevated feeding can help prevent health issues in large dog …

Jcati Composite Delaminator, Payden Coffman

All Undergraduate Projects

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 …

Ideal Lacrosse Stick, Josh Beck, Tyler Skoloda, Noah Reed, Stanley Dembosky

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 …

Senior Design Proposal For Brakes Subsystem 2019-2020, Jasmine Zogheib, Zachary Demetriades, Devin Seay

Williams Honors College, Honors Research Projects

This report concentrates on efforts to design a new braking system for the Zips Formula Electric Race Team. The improvements to the braking system will be based upon previous years’ official designs along with optimizing for predetermined criteria. The design will be influenced based on design factors of the car such as weight, center of gravity, wheelbase, and integration with other systems of the car.

Tabletop Mechanical Tester, Jamie Dombroski, Brian English, Richard Leffler, Andrew Shirk

Williams Honors College, Honors Research Projects

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 …

Design And Optimization Of Dynamic System For A One-Kw Free Piston Linear Engine Alternator-Gensets Program, Nima Zamani Meymian

Graduate Theses, Dissertations, and Problem Reports

In power/energy systems, free-piston linear machines are referred to as a mechanism where the constrained crank motion is eliminated and replaced with free reciprocating piston motion. Depending on the application, the piston motion can be converted into other types of energy and includes compressed air/fluid, electricity, and high temperature/pressure gas. A research group at West Virginia University developed a free-piston linear engine alternator (LEA) in 1998 and have achieved significant accomplishment in the performance enhancement of the LEAs to date. The present LEA design incorporates flexure springs as energy restoration components and as bearing supports. The advantages of using flexure …
