P. 1 Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition Modeling Week 2 Day 3

P. 2 Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition Modeling What is a model? Why should your group think about creating a model?

P. 3 Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition Models can be: Drawings Equations Numerical Simulations Mock-ups Prototypes

P. 4 Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition Drawings Sketches CAD Key AutoCAD Solidworks ProEngineer

P. 5 Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition Equations Analytical – derived from theory Empirical – observed from experimentation Graphical

P. 6 Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition Numerical Simulations ANSYS - Finite Element Analysis Flotran - Computational Fluid Dynamics MADYMO – Car Wreck Injury Simulation MATLAB – Simulink Minitab – statistical modeling

P. 7 Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition Mock-ups A physical model of an idea to show the spatial relationship of parts. Not fully functional Not necessarily to scale

P. 8 Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition Prototypes  The first fully functional and full scale representation of a design. - Tools and Tactics of Design

P. 9 Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition Purpose of Modeling Gives you the ability to test, prove, and disprove the feasibility of ideas Better understand the problem Refine your concept Prove to yourself and your group that an idea will work Fewer mistakes later Helps avoid wasting time and money

P. 10 Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition Mock-up or Prototype?

P. 11 Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition Part Mock-up – Part Prototype Only the pickup mechanism was completely prototyped. Model was continuously revised until the final working model was completed. Model was produced using cheap materials that were quickly and easily changed or replaced.

P. 12 Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition Examples of Materials for Mock-ups and Prototypes Erector Sets Legos Popsicle sticks Welding rod / coat hangers Cardboard Hot glue Tape

P. 13 Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition Parts and Materials Parts can be purchased commercially or someone within your group can manufacture them.

P. 14 Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition Purchased Parts Parts can be found at the FEH store, Wal- Mart, Lowes, craft shops, bike shops, flea- markets, hardware stores, the kitchen cabinet, from your closet.... Purchased parts can be used for a purpose other than what they were originally manufactured for, or they can be modified. Purchased parts can easily be replaced.

P. 15 Engineering H193 - Team Project Spring Quarter Gateway Engineering Education Coalition Custom Parts Take more time Can more specifically meet your needs Difficult to replace Can require a great deal of technical skill Can be much cheaper than purchased parts
