It's not common for U.S. engineers to re-engineer a product designed in Asia. But that's exactly what engineers at Enidine, which specializes in shock and vibration technologies, did recently with a long-stroke, high-performance shock absorber. Norm MacKenzie, product line manager for the new PRO Long Stroke Series units, explains that Enidine acquired the extension to its line of standard hydraulic products from a Korean company. "The original product was only capable of about 30,000 cycles," he explains. "So although it's not usual for us to work this way, we redesigned the piston head and foam accumulator to get around 5 million cycles." Enidine just released the product, which can accommodate from 75 to 2,300 in-lbs. Target applications include pick-and-place robotics and plastics molding equipment.
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
