MBTA (Massachusetts Bay Transportation Authority
Time:
July 2016 – December 2016 Location: Somerville, Massachusetts Role: Assistant Mechanical Engineering Intern The MBTA is a public agency responsible for operating most, if not all the public transportation services in the Boston. At the MBTA, I had the opportunity to work with other engineers to learn about the locomotives responsible for taking us around the city. Main Project: To Investigate the maximum load threshold of a locomotive brake and create a cost analysis for future manufacturing Task: Create a cost analysis project for engineers to evaluate optimal manufacturing options for locomotive's steel wheel break Steps: 1.Conduct thorough investigations of spent brakes at different locomotive shops 2. Identify the difference between a usable and an unusable brake 3. Perform stress tests on SolidWorks with different material and types of stresses to find the amount of time it takes to spend a brake 4. Determine whether the investigated brakes were thrown away prematurely 5. Write a report on how many usable breakes were scraped away and complete a cost-anaylsis spreadsheet on the potential resource saved 6. Present to head engineers about the project Skills Developed: Long term investigation, Teamwork and communication, SolidWorks, Project management You can find a better look/understanding of this project by clicking on this link |
