The Challenge
The Army needed to downsize a huge Army communications system,
for which the framework alone weighed 1,000 lbs, to make it easier
to transport - and redesign the framework to fit on two trucks
instead of four.
The Solution
Lead mechanical engineer Gene Curran, modeled the framework to
meet military test requirements, and then performed linear static
analysis on the redesigned framework over several iterations --
reducing the weight with each iteration.
Within 60 days of starting the project,
a 400-lb prototype was fabricated. Although only 40% of the weight
of the original, the new design was twice as strong. And before
Curran had the chance to test the prototype, events intervened
and it was shipped out with the first unit of military personnel
to Operation Desert Shield. Even with a 30% overload, the system
experienced zero failure in action.
Summary and Metrics:
- Reduced the weight by 40%
- Doubled the strength of the original design
- Accurately predicted real world behavior of the model

"Even with a 30% overload,
the system experienced zero failure. Our team was very
proud of our prototype."
