Perfect Design Engineering Example

Chuck, this story is a great example of what good design engineering is all about. Here, Moog is taking a product that's come into increasing usage since 9/11 -- the roadway barrier for security -- and taking it to the next level with an elegant solution that replaces hydraulics with more reliable servo-motor control.

Excellent point Alex. Be sure to check out the video, too - it's pretty amazing.

I think the video shows the need for one more feature, a net to catch the debris!  The USN used to have a big wire mesh net to protect aircraft on deck from those that were in trouble during landings on a carrier.  Modern carriers have an angled flight deck that precludes this requirement.

In the video the leading edge of the barrier is like a knife edge that slices into the moving vehicle.  Perhaps a flat plate type front to absorb impact would result in less debris passing the barrier and shearing of the vehicle.  

I would be interested to hear what some of the orginial design criteria were.

Since 2009, K12 Defense has perfected the conversion process, utilizing Moog's linear servoactuator -- which use - in barriers - we introduced to Moog. Moog's design engineers were in our Arizona facility yesterday testing a new device in our wedge plate barriers.  We have successfully converted over 50 wedge barrier with our EM+ system for the military and currently place our EM+ system in drop arm, other wedge barriers and gates.

Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
A decade from now, firmware development may be nothing more than software integration, grabbing vendor and third-party components, and meshing their APIs together to form a final system.
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.

Researchers in Australia think new types of plastic materials instead of silicon may be the key to building more efficient solar cells.
