Engineers at Silicon Graphics designing the company’s new Altix[R] 3700 BX2 supercomputer used software to find the reasons for shock and vibration problems in the design. The problems stemmed from planar packaging of the pc boards, which made it difficult to build in structural elements for handling the shock and vibration. Deflection of the hardware created a shear load on the joints. Software pinpointed the problem and showed the path to the solution.
Using a combination of in-house testing (vibration and dye-and-pry tests) and PTC’s Pro/Mechanica finite element analysis software, engineers found the point of maximum deflection. They had measured different sites along the boards with accelerometers. Their conclusion was that the failure was in connectors under the stiffener in the chassis.
The original stiffener design they used was rigid enough, says team leader Steven Dean. But they had substituted a sheet material to reduce costs, and found the material couldn’t handle the movement. Dean compared the problem to the harmonic-frequency issues automakers and jet-engine manufacturers have.
The solution: Reconfigure the stiffener elements.
“It was a hard problem to find,” Dean says. The software was essential to resolving the issue.
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
