ME2525 - Machine Element Design

Students will learn the fundamental theory of mechanical design and will learn to apply this in the design and analysis of a variety of machine elements. Methodical design process is emphasized. The course is split into two parts, the first addressing the process of design and fundamentals of stress, strain, material properties, failure theories, fatigue, and fracture mechanics as they apply to simplistic example components. In the second section, such design theories are applied in the analysis of several key machine features (e.g. notches, holes, keyways, welds) and components (e.g. shafts, bolts, screws and gears).

Learning Outcomes

• understand the fundamental scientific principles of mechanical design (stress, strain, material properties, failure theories, fatigue phenomena, fracture mechanics) and their importance and use in design analysis (EAC1.1a);
• develop practical experience with the function, design and analysis of actual machine components including prediction of their life and failure (EAC1.3a, EAC2.2b,c,d);
• practice systematic approaches to mechanical design and analysis procedures (EAC1.6a, EAC2.1a, EAC2.2e);
• implement standards in the design of machine components, understand their purpose, and be exposed to examples that highlight how standards are formulated in engineering practice (EAC1.6b, EAC2.1f);
• produce analysis briefs, design sketches, and assembly and detail drawings that clearly communicate machine element design and analysis (EAC3.2b).
