Gamma-Type Stirling Engine
Design, Fabrication, and Testing
Starting with raw materials and design constraints, I designed, analyzed, and fabricated a Gamma-Type Stirling Engine as part of a machine design and manufacturing course. From concept to execution, I integrated engineering principles with practical constraints to create a fully functional system. Using SolidWorks, I developed 3D models, analyzed structural integrity, and optimized the design to ensure feasibility and efficiency.
To balance precision with creativity, I incorporated some custom designs into key components such as the flywheel and bedplate. I also created detailed engineering drawings with GD&T to ensure proper fit and functionality within machining tolerances.
Fabrication & Machining
Throughout the manufacturing process, I machined each part using CNC mills, lathes, bandsaws, and drill presses, applying techniques such as Mastercam and G-code generation for CNC automation. Some components required additional precision work, including [mention any unique machining challenges].
After fabrication, I polished and assembled each component, testing subassemblies before integrating them into the final system.
Final Testing & Results
On the final test day, the system was tested using the heat from a blow torch. The design successfully ran at 1888 RPM, attaining 2nd position. This project reinforced my skills in design-for-manufacturing, tolerance analysis, and hands-on problem-solving.
