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.
Some cars are more reliable than others, but even the vehicles at the bottom of this year’s Consumer Reports reliability survey are vastly better than those of 20 years ago in the key areas of powertrain and hardware, experts said this week.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
While many larger companies are still reluctant to rely on wireless networks to transmit important information in industrial settings, there is an increasing acceptance rate of the newer, more robust wireless options that are now available.
