Here are some examples of the projects and homework I have done at University of Illinois where I obtained my Bachelor of Science in Engineering Mechanics degree...
I joined a research group to design an advanced electrosurgical knife during my junior and senior year. The goal of our project was to design, build, and test a working prototype of the electrocautery device that can acquire and utilize real-time information about the tissue to regulate power and prevent charring and damage. I was mainly focused on designing a sensor and writing a program to obtain real-time information about changes in the spectrum of molecular transmission as the tissue chars using Fourier transform infrared spectroscopy. As the program was able to detect the increase in alkene bonds as the tissue chars by the sensor, it is possible to do the surgery more safely. With my dedication on this project, I have been granted the T.A Peebles award, which is given to a student who displays proficiency in automatic control systems.
SOlar Powered Bike Rack
For my senior design project, I joined a team with 4 other members to complete a solar bike rack prototype to be implemented on the university’s campus. This solar bike rack is required to protect locked bikes from the elements, while also providing light at night. Light is a necessity because many racks are placed in locations with little to no light, complicating the locking procedure and raising safety concerns.
Our solution was split into two parts: the structural and the electrical components. The structure consists of four vertical posts, which support two diagonal beams on either side of the shelter. These diagonal beams support four cross beams, which support the roofing material and solar panels. Metal plates with bolt holes are welded to the vertical posts to provide for simple, sturdy installation to a concrete landing. I was mainly focused on the electrical components consisting of two batteries, two solar panels, LED lights, wires, and a controller. The batteries, solar panels, and lights are each connected in parallel to the controller. The controller regulates every electrical subsystem and the solar panels are mounted to the two center cross beams. These components were assembled into a successful prototype, excluding for the roofing material due to budget concerns.
Finite Element Analysis
I took this class during the second semester of my senior year. I learned finite element method and its applications to engineering problems such as truss and frame structures, heat conduction, and linear elasticity; use of application software; overview of advanced topics such as structural dynamics, fluid flow, and nonlinear structural analysis. I used Matlab to complete programming assignments and projects involving systems of spring, heat convention/conduction, truss, etc. An example of the programming assignment to solve heat FEA problems is attached below.
