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. See www.k12defense.com
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.
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.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
