BBC - How car design has gone virtual

In the past, cars were built almost by a process of trial and error. You built a prototype, then tested it to find out what worked and what didn't. Nowadays, much of this work is done by computers. 

Theo Leggett has been talking to Stephen Remondi, chief executive of Exa Corporation, to see how 3D simulations are being used by designers to refine their work in the virtual world before a single car panel has been built in the real one.

SAE International - Aero-slick Land Rover Discovery sheds 1,058 lb, gains features

JaguarLandRover engineers continue to achieve significant vehicle mass reductions, this time with the new generation Land Rover Discovery. Shifting to aluminum construction for the bodyshell instead of steel and complemented by an intensive light weighting program for the whole car, has yielded a remarkable 480 kg (1,058 lb) saved compared with the previous model. This exceeds even the 420kg (925 lb) reduction of the Range Rover in 2012 when it was switched to an aluminum-intensive architecture.

Le châssis de Onroak Automotive fait partie des quatre sélectionnés par l’ACO, la FIA et l’IMSA répondant au nouveau règlement de la catégorie LMP2 qui entrera en vigueur en 2017.

3D CAD World - Move from wind tunnel testing to simulation-driven design offers typical automakers more than 500% ROI

Moving from wind tunnel testing of physical prototypes to simulation-driven design processes can offer typical automotive OEMs more than 500% ROI (return on investment), according to research from Tufts University’s Gordon Institute for engineering management.

Automotive Supply Chain - Designing Trucks for Platooning

Platooning improves fuel economy by at least 10% and Exa simulations calculate optimum distance as 30 feet, with added potential new economy available by booking best slot in platoon.

If Tesla wants its planned electric truck to come with enough range acceptable to haulage fleets, it might need to accelerate research into platooning. Platooning is when smart trucks connect digitally to travel in close convoy, in order to improve overall fuel economy.

Automotive Engineer - Exa's technical director, Kevin Golsch, explains how simulation is helping to improve efficiency in truck platooning

“If Tesla wants its planned electric truck to come with enough range acceptable to haulage fleets, it might need to accelerate research into platooning. Platooning is when smart trucks connect digitally to travel in close convoy, in order to improve overall fuel economy.

Automobil Konstruktion - Simulation statt Klimawindkanaltest

Das heutige Infotainmentsystem ist das Gehirn eines modernen Fahrzeugs, das dem Fahrer wichtige Informationen über den Betriebszustand und das Umfeld zur Verfügung stellt. Es hilft dem Fahrer, ans gewünschte Ziel zu navigieren und dabei das Fahrzeug sicher zu bewegen. Aufgrund des hohen Kühlungsbedarfs, den die komplexe Elektronik insbesondere in heißen Klimazonen hat, erfordert dieses kritische System zusätzliche Aufmerksamkeit im Hinblick auf das Wärmemanagement.

DESIGNING TRUCKS FOR PLATOONING

If Tesla wants its planned electric truck to come with enough range acceptable to haulage fleets, it might need to accelerate research into platooning, smart trucks connecting digitally to travel in close convoy to improve overall fuel economy. 

Kevin Golsch, technical director of Exa Corporation, said the benefits of drafting in this manner have been proven. In April this year, a fleet of trucks from all of the major European manufacturers linked via Wi-Fi to take part in a Dutch-organised transcontinental drive.

Exa Reports Second Quarter Fiscal 2017 Financial Results

"Second quarter revenue was within our guidance range, reflecting the predictability of our licensing model. In addition, profitability exceeded our guidance range as we continue to realize the leverage in our operating model," said Stephen Remondi, President and Chief Executive Officer of Exa. "We believe that our focus on license revenue, as we continue the conversion of project-based customers to ExaCLOUD-based recurring license customers, will drive stronger year-over-year revenue growth in the second half of the year.

Just Auto - What will a Tesla electric truck look like?

Just what would a Tesla electric freight truck look like? It's a question that many in the auto industry have been asking after the latest visionary bulletin (Master Plan, Part Deux) from Tesla founder and talisman Elon Musk. 

Tesla CEO Elon Musk wrote in his Master Plan, Part Deux, that future electric models from Tesla will include a full-sized truck. He promised that it would "deliver a substantial reduction in the cost of cargo transport" as well as being safer and "really fun to operate".

Ales Alajbegovic, VP Ground Transportation at EXA is in a position to have some inkling of the design that may be coming down the Tesla CV line (and unveiled as early as next year). EXA already works with Tesla to reduce aerodynamic drag on its passenger vehicles, as well as truck firms and semi-trailer makers to help reduce air drag and cut down on the substantial fuel costs.

The Newswheel - What Is That Painful Thumping Noise When I Open My Window and How Do I Get Rid of It?

So, as you hurriedly raise the window while yelling at your friend to just ask when they are feeling too hot next time, you wonder, “What the heck was that noise?”

That noise is known as Helmholtz resonance, or more colloquially, “wind throb.” Putting it simply, the noise is generated in the same way you make noise by blowing across the mouth of a soda bottle.

AMN - New Collaborative Partnership Between DENSO and Exa Aims to Transform how Vehicle Manufacturers Work With Suppliers

Exa Corp., a global innovator in simulation software for product engineering, and DENSO Corp. have announced a new collaborative partnership that will transform the way carmakers have traditionally interacted with suppliers. The partnership enhances the product development process by moving key engineering and design work from automotive suppliers to a certified simulation-driven process that can be done much earlier in the development process, reducing the number of late-stage vehicle design changes.
