MCEN 4045 focused on developing a design proposal and constructing a prototype, while MCEN 4085 focused on completing the design and delivering results.

Rotating Vibration Pendulum Absorbers and Workflow

My team conducted a feasibility study on the use of rotating pendulum vibration absorbers (RPVAs) to counteract peak torsional vibrations within the crankshaft of an aviation engine. We used both project management and technical skills to organize literature reviews, define problems based on customer information, develop and validate vibration simulations, and recommend decisions for the client.

Contribution

My contribution focused on the construction of an accurate torsional vibration model, verified by real-time observational data. I utilized fourier analysis to extract information from in-situ data and compare vibration amplitudes in the frequency-domain.

Torsional Vibration Model and Results Compared to Observation

Our team successfully delivered a prediction of potential amplitude reduction if a 4th-order RPVA was utilized in the engine. Ultimately, development of an RPVA requires too much resources, and the client ultimately pursued the development of a brand-new V-twin aviation engine
