Design


Steering Rack and Pinion
for Blue Jay Racing 17XT, 2020

The steering rack and pinion converts the driver's torque on the steering wheel to linear force onto the tie rods to steer the vehicle. After reviewing the past 5 years of the team's rack design, I determined the major previous design failures and recalculated the steering system's loading conditions from experimental strain gauge data. Major changes from previous years include the support tube to eliminate sleeve bearing alignment, 33% weight reduction due to the new bimetallic rack, and an ergonomic 210 degrees lock-to-lock steering angle. Designed and analyzed in Solidworks for desired FOS 2.0 and expected 50-60 hour lifetime.

Mini Crane Boom Design Project
for Mechanics Based Design Laboratory, 2020

Working with two other mechanical engineering students, I worked to calculate loads, determine factors of safety, design the beam and a transmission system, CAD, and select materials for a small crane intended to lift 10 pounds at 18 inches off of a table. Unfortunately, we were unable to construct the final design due to the COVID-19 school closure. Click here to view the assembly drawing and component list of the crane.


Brake System
for Blue Jay Racing 16XT, 2020

As Controls lead of Hopkins Baja, I designed the entire brake system, which includes the pedals, bias bar, master cylinders, brake line, calipers, and rotors. Following the goals of the overall vehicle, some components are off-the-shelf for easier manufacturing and serviceability. I utilized Solidworks to design some components, perform FEAs, and package the parts into the larger car assembly. Click here to view my presentation on the system.

Goals - The goals of the 16XT brakes are to provide a reliable system to pass brake check, accommodate the additional 4WD components in the footbox, and to improve load verification of the system.

Data Collection - Instead of simply estimating like in previous years, we conducted tests to more accurately define our loading conditions. For example, we experimentally found the coefficient of friction between caliper pad and rotor to be 0.31. With numerous inputs, including a desired factor of safety above 2 for both front and rear brake lines, the system requires 3000lb-in on the 16XT rotors to pass brake check. 

Design - The 16XT pedals are simple and easy to manufacture, floor mounted this year to improve driver visibility and reduce their profile. Rather than last year’s custom calipers and master cylinders, which led to manufacturing and performance failures, we switched to off-the-shelf components. Packaging constraints drove the selection of both the Wilwood MC Karts (0.5in bore), a reliable and small model that Blue Jay Racing has used in the past, and the Polaris Sportsman Calipers. Improving weight reduction over last year’s rotors, a leading spoke cutout design decreased moment of inertia by 4%. Both the rotors and calipers are mounted to axially float into the path of least resistance. 

Analysis - With the collected data and well defined loading conditions, FEAs were conducted on the manufactured pedals and rotors with 100lb applied at the pedal, creating 3000lb-in on the rotors.

Validation - We conducted several brake checks with the system assembled on the car, simulating the competition event. Bleeding the 3AN brake lines to obtain sufficient incompressibility of the DOT3 fluid was a challenge, so we placed pressure gauges on each line to verify when we obtained 750psi in the rear line and 1400psi in the front due the driver pressing on the pedal. With an almost complete brakes testing rig, we can confirm the torque to turn the rotor at certain pressures.

Center Driveshaft
for Blue Jay Racing 16XT, 2020

With a major rules change for the 2020 Baja SAE competitions, the Blue Jay Racing team switched to a 4WD vehicle for the first time in history. I took on the role of designing the car's center driveshaft, which provides power to the front differential from the transfer case. We will splice and extend a Polaris driveshaft, covered in SAE rules compliant casing for both the shaft and joints.

Automated Sensor Resistance Tester
for FreshAir Sensor, 2019

FreshAir Sensor makes patented devices to detect tobacco and marijuana smoke in hotels and apartments. After printing the chemical solution on each plate, the resistance must be tested on all of the manufactured sensors. The device pictured clamps down onto the plate of sensors and contacts them with spring pins. PCB board (which I did not make) connects to an online portal and indicates which sensors are outside of the desired threshold. The device automates the process of testing each sensor with a multi meter to reduce manufacturing and production time.

Papers


Independent Research
Twisted Ribbon Geometry and Design (2020)
This paper is written for the Antioch Recovery Project, part of the Classics Research Lab at Johns Hopkins University. It serves as a journal surrounding my research into the Twisted Ribbon border pattern of the Antioch Mosaics, a meandering flat ribbon waving across the mosaic in a repeated manner. While there is thought to be no major significance to the pattern itself, it represents “the movement towards ornamental complexity” in the Antioch mosaics, “which was born in the late second century.” This paper will focus on the twisted ribbon that transverses sinusoidally, analyzing the pattern in a geometric, design, and mathematical context.

Hedonic Price Model of New England Ski Areas (2019)
Using a database of 60 New England ski areas, the correlation between several primary resort characteristics and the 2018-2019 adult day ticket prices is analyzed. A hedonic price model is used to run an OLS regression on the data and determine the importance and significance of 13 variables. This study determines that ski area size (including number of trails, skiable acres, and vertical drop), the snowmaking capabilities of the mountain, the number of nearby restaurants, and the proximity of a ski area to local residents and population centers have the greatest positive influence on ticket price. The hedonic model is also used to form a ranked list of ski areas in New England by their expected ticket price, representing resort quality, and how this compares to their actual ticket price, representing resort value.This study can provide valuable information to ski area management and tourism offices across New England, who can better understand the motivations for alpine skiing customers in the region.

Trump Twitter Discourse (2019)
Donald Trump, the Republican Candidate in the 2016 United States Presidential election, used Twitter to insult and troll his opponents, particularly Democrat Hillary Clinton. By looking at 230 @realDonaldTrump Tweets which address Clinton during the campaign, this study analyzes Trump’s statements sociolinguistically and statistically, comparing the tweets’ structure and rhetoric between two time periods. Once Clinton became his primary opponent, Trump’s tweets became slightly more multimodal, the number of tweets addressing Clinton decreased, and the average length of these tweets also decreased. However, there was no significant change in Trump’s rhetoric toward Clinton. Further analysis reveals that Trump’s shorter tweets gained more popularity, as well as statements referencing Clinton’s email scandal. These comparisons and linguistic analyses of Trump’s statements provide insight into his communication process and campaign strategy during the election.
