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.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
