Symbiotic Structural Control and Health Monitoring System using Magneto-Rheological Damper for Seismic Mitigation

By: Michael Calder and Omar Plata

Mechanical Engineering

Faculty Advisor: Dr. Zhaoshuo Jiang

Structural health monitoring is a means to use dynamic responses to determine current and post-event structural conditions. Structural control received a lot of attentions for reducing or eliminating undesired vibrations for civil structures. Traditionally, structural health monitoring and structural control are independently applied. Leveraging structural health monitoring and structural control systems has great potential to provide a more timely and sophisticated solution to the aforementioned problems. This project intends to develop an integrated structural control and health monitoring system which allows the structures to react and adjust to external loadings automatically.

O.M.I.S.R.O Device

Faculty Advisor: Dr. Thomas Holton

The purpose of our design project was to improve upon a single aspect of a wave-energy converter, specifically the way that an ocean wave's oscillatory behavior can be translated into a single directional output. Our design aims to accomplish this by converting both clockwise and counter-clockwise motion, and by inference an alternating input in both directions, into a constant direction of rotation about a shaft.The implication being that whenever this design can appropriately be applied to capture mechanical oscillatory motion, it can be converted into torque in a single direction. The design can be scaled up or down depending on the application, which can range from a large ocean-wave energy converter to a small handheld ratcheting tool.

Mechanical Engineering

Faculty Advisor:

Our project is on assistive seat which is designed to help older people and people with joint problems to get in and out of a regular chair. The seat uses air bladder to lift the seat up and down by pumping air into the bladder. The air flow is controlled by on/off switch.

3D Printed Prosthetic Hand

By: Daniel Pacifico, Chris Lambert, Ryan Hendrickson, and Dzung Nguyen

Mechanical Engineering

Faculty Advisor: Dr. Thomas Holton

The scope of this project is to create a cheap, reliable prosthetic hand that is accessible and easily customized. This prosthetic will target individuals who have lost part or all of their hand but have retained muscle movement in their forearm. The hand will be attached to the forearm and will be controlled using emg or electromyograph sensors which will read muscle movement in the forearm. Using this design, the user will be able to perform fine and gross motor skills without incorporating a secondary control system e.g. voice control or flex sensors attached to the uninjured hand. When the user moves his or her hand, the emg sensors will recognize those movements and communicate with an Arduino over bluetooth. The Arduino will mimic those gestures in the prosthetic hand using several servo motors placed in the prosthetic hand's wrist.

Linear to Rotational Motion for a Reciprocating Engine

By: Daniel Savage, Vincent Fung, Ram Sunwar, Abdirazak Jama, and Jamal Alnagem

Mechanical Engineering

Faculty Advisor: Dr. Thomas Holton

We designed a mechanism to translate purely linear piston motion of an internal combustion engine to rotational motion for an output shaft. This design reduces the overall size of a reciprocating engine compared to one using a traditional crankshaft, reduces the number of engine parts, and reduces friction and unwanted forces on egnine cylinder walls.

Adjustable Bike Seat

Mechanical Engineering

Faculty Advisor: Dr. Thomas Holton

This project is an attempt to increase rider efficiency while on a human-powered bicycle. An anticipated outcome is to make bike riding more appealing; a result which would help decrease greenhouse-gas emissions as well as reduce health complications among the general population. The solution will need to be light weight, easy to use, and increase rider power output in a noticeable magnitude. We have decided to use a gas-spring system to allow a quick adjustment of the seat height to maximize rider power out-put in relation to the slope of the terrain the rider is on. /

Dishwasher Improvement Protype

By: Michael Magee, Brett Hendrickson, Erika Reyes, and Ricardo Liceo

Mechanical Engineering

Faculty Advisor: Dr. Thomas Holton

Virtually all dishwashers regardless of price range have a common flaw. In using a single rotary bar of water jets, the corners of the machine are not sprayed as effectively as the inscribed circle. In Addition, The use of water pressure to rotate the bar results in all streamlines radiating outward from the center, leaving one side of the dishes virtually untouched by the high pressure jets. The goal of the project was to prototype a concept that would allow the entire rack to be reached equally. This has been achieved by placing several small spindles, each containing three jets on a moving rack that sweeps front to back across the cavity of the machine. Each individual spindle is spun using water pressure, but by also moving the spindle, issues of the streams radiating outward are resolved.

Longboard Brake System

By: Nicholas Breyfogle, Jordan Wells, and Mario Lazaro

Mechanical Engineering

Faculty Advisor: Dr. Thomas Holton

Longboards and skateboard rely on the rider to provide the force to accelerate and decelerate. Our project is to design a mechanical braking system built into a longboard in order to provide additional braking force, since in many cases the braking force from the user consist of dragging their shoe soles on the ground which isn’t enough to safely stop. The requirements are to create custom mounts and calipers attached to modified trucks(wheel axis) in order to push against a brake rotor that we will attach to the wheels. The main challenges are tight clearances and lack of space underneath the board and providing enough braking force. Our goal is to create a system that is easy to install on any longboard and ease and safety of use for the rider.

Inductively Heated Vacuum Flask

By: Deryl Marvive and Kevin Kor

Mechanical Engineering

Faculty Advisor: Dr. Thomas Holton

The project consists of a two man team, a mechanical and computer engineer, which will design a vacuum sealed flask which is heated through induction with a base providing the heating resistance. The proposed plan is to design a flask that can be placed on to a heating base which will inductively heat the plate embedded in the flask. Construction of the cup and base requires a mechanical engineer to prototype via Solidworks and properly implement a double walled insulated vacuum seal that will safely heat the contents via induction heating. The mechanical engineer will then need to construct the cup using various processes to mold and construct the the cup. The computer engineer’s goal is to design the electrical schematic and program the microcontroller that interacts with the user. This interaction is includes, but is not limited to, properly heating the contents at a desired temperature and correctly reading the temperature of the contents.
