Mechanical Design and CAD Modeling

1. Task Clarification (25%): We need to: (a) Clearly define the problem and objectives, (b) State assumptions (load conditions, geometry, materials, etc.), (c) Prepare a rough project schedule, (d) Specify what you intend to design or modify (vehicle pickup system, etc.)
2. Calculation (25%): Perform complete mechanical design calculations, including: (a) Load Analysis, (b) Calculate all forces acting on the shaft, (c) Create Shear Force and Bending Moment Diagrams, (d) Bearing Selection, (e) Define required operational life (hours), (f) Follow Mott’s bearing selection method, (g) Select Deep Groove Ball Bearings, (h) Compute actual bearing life and verify suitability
3. Shaft Design: Include effects of shear, bending, and torsion, Consider stress concentrations (keyways, bearing seats, etc.), Choose an appropriate shaft material, Determine minimum and final diameters, Ensure factor of safety and feasibility
4. Modeling (25%): Use CAD (preferably CATIA V5) to Adapt a Pickup vehicle model to your chosen assumptions (size, load, etc.), Modify the chassis, bodywork, and axis mounts, Integrate chosen bearings and adjust connected parts accordingly, Add material properties to parts, Shape your own vehicle variant (e.g. sedan, convertible, etc.), Assemble all components into a complete prototype model
5. Presentation (25%): You must give a 5–10 minute presentation that covers all subtasks (1–4), Explains your methodology, reasoning, and modeling process, Uses CATIA V5 during presentation (recommended), Ends with a short discussion
