W06: CAD and Engineering Analysis (Summer 2012)
Using a CAD program each team prepares a 3-D solid model with sufficient detail for part fabrication.
Each team presents a critical analysis of the design. Determine the areas that are most likely to fail first and show proper design by determining appropriate safety factors. What are the potential engineering and/or manufacturing problems? Estimate basic features such as weight. (Note: for FEA results present calculated stresses in terms of the corresponding safety factors, e.g. a graphic color spectrum represents the safety factor magnitude.)
The design analysis should address the following areas as appropriate: Power consumption; Strength of materials analysis for fasteners and critical load bearing elements; Fatigue analysis for critical load bearing elements; Stability during operation; Kinematic analysis; Dynamic load analysis; Control methods and algorithms; Material selection; Safety; Human interface; Tolerances; Performance analysis and prediction; Other analyses as needed.
