Movies portray the pleasure of drivers racing down the road with windows open or the top down, but most people would rather have near silence than the roar that comes with that wind-in-the-hair feeling. That's made sound and vibration testing a more important part of vehicle analysis. It also involves far more engineers.
"Originally, the community of sound and vibration experts was small, but now the number of engineers who need to deal with sound and vibration is growing exponentially," says Gabriella Cerrato Jay, technical director at MTS System Corp.'s software and consulting group. As more drivers expect to mimic the sound quality they're used to at home, stereo systems and voice recognition for hands-free phone calls will become more common. To help engineers find information about their noise and vibration issues, Jay has started a blog that includes technical articles on various topics, not all of them automotive. Several other experts in sound and vibration analysis also post to http://rbi.ims.ca/4398-534. MTS engineers blog about the topic at http://rbi.ims.ca/4398-535.
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
