This is an important step forward. Bearing hot boxes have been used forever. I can remember them being used in the '70s, and they were mostly good for spotting existing problems, rather than heading off potential issues.
I wonder how this is done, exactly. Sound is applied, and the resulting frequency is measured. If it doesn't match the freq tolerance range, the wheel is rejected? Or, can the sound sensing locate the actual flaw? Like a sonar technique.
I used to know a few people that repaired industrial equipment, including train wheels. Mostly welding fractures or breaks back together. How would repairs work with this system. It almost seems like a waste to throw out a whole wheel.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
