Mechanical System Design Fundamentals
Machine Design Models
1. Create appropriate machine design models that represent real structures and components.
Free Body Diagrams
2. Draw a free body diagram of a structure of machine component. Show the loads and calculate the reactions. Draw shear moment diagrams.
Stress from Combined Loadings
3. Calculate stress in machine components due to combined loadings.
4. Estimate the deflection of structural members under combined loading.
Application of Static Failure Theories
5. Select an appropriate static failure theory for a brittle or ductile material and apply it to predict failure loads and safety factors for various geometries and loading conditions.
6. Analyze the stresses in pressure vessels, press fits, curved beams, bolts, and bolted joints.
7. Calculate buckling predictions for statically loaded compression members.
Cyclically Loaded Members
8. Construct S-N and Goodman diagrams for cyclically loaded members, calculate mean and alternating stresses and predict safety factors for infinite or finite life.
Design to Prevent Failure
9. Design machine members to prevent static, dynamic or fatigue failure. Integrate several components in a system to meet design requirements.
10. Gain experience using commercial FEA software to create models of simple structures and machine components. Solve these models to determine deflections and stresses, and understand how to interpret the results for engineering application.
Structured Problem Solving
11. Students will gain experience using a structured problem solving technique (e.g. SAFER) to solve machine design engineering problems.
12. Students will gain increased understanding of machine design problems by exploring solutions using the ConVerSAnt method.
13. Students will apply machine design analysis concepts to a real-world problem and document their analysis through well designed figures and graphics as well as a technical report.
