CAD - University

During my first year at university, I had to design a Stirling engine in CAD, which I had previously manufactured during my practical sessions.

However, rather than manufacturing the physical product, I now had to create a CAD model incorporating my own design changes.

This involved using outdated and incorrect technical drawings to design the parts.

As a result, I had to carry out research and calculations to correct the drawings. I also had to redesign the flywheel to my own specifications.

After completing my research, I had to design the individual CAD parts, assemble all the components and produce technical drawings of the assembly, including a bill of materials.

Another separate part of the project involved analysing the bolts used in the design and determining whether improvements could be made in the future.

However, I had to ensure that any alternative materials could still withstand the operating temperatures of the Stirling engine.

After researching the different materials available, I decided that nylon, steel, brass and aluminium were the most suitable options to investigate.

I then evaluated each material through a thermal study, while also considering cost and manufacturability.

Following this analysis, I concluded that nylon was the best material for the application.
