Modeling as a prelude to Prototyping

Very good description of the process Jon.  You mentioned iterating through the modeling process and tests once a candidate motor is selected.  I would suspect the requirements for prototyping could be reduced but not completely eliminated.  And good model based testing would go a long way toward making sure the prototypes were very close to a final design and implementation.

I am curious as to how the models might be updated with feedback based on prototype testing. Validation of the model inputs based on testing the prototype might be useful as well as testing failure modes.

One thing we strive for in testing is to characterize the failure modes and try to insure the system degrades gracefully under loads.  Catastrophic and unexpected failures are to be avoided at least in early testing but it is useful to know just how the system can fail.

I usually learn a lot about a system when I have to examine in detail any unexpected failures.  Frequently this is related to an assumption on my part that was incorrect and inadequately tested before hand.  Does this happen in the models before prototyping?

How do you characterize model fidelity with respect to the real world?  It seems a great deal of experience is required to model complex systems with a high degree of accuracy.

What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
