The first project introduces the structure of projects in this course; introduces the design approach; reviews and begins to apply statics and stress analysis skills from prerequisite courses to design; introduces finite-element analysis; and provides an opportunity to work out any issues with fabrication methods.
The second project comprises a challenging, open-ended problem: design of a single component for mass efficiency. Success requires sophisticated application of the design approach, including statics analysis using free-body diagrams; stress, deflection and buckling analysis using simplified models and finite-element analysis; and testing of both low-fidelity and functional prototypes.
The third project introduces simple models of electric motors and gears; applies these models to selection of a motor operating point and gear ratio; and introduces the design of experiments to identify important system characteristics.
The fourth project comprises the challenging, open-ended design of a motor-driven machine to maximize electromechanical performance. It requires application of the Design Approach to complex problems in a team setting; effective incorporation of multiple custom and catalog components into an assembly; and sophisticated use motor and gear models, power analysis, and mass-efficient component design.
