BLOGO - Tesla Model 3: baciata dall'aerodinamica

La gamma Tesla sta crescendo velocemente: lo conferma l’arrivo della Model X ed il prossimo arrivo sul mercato della nuova Model 3, la nuova berlina media a propulsione elettrica della casa americana. Quest’ultima sarà in grado di percorrere una distanza pari a 345 km con un “pieno” della sua batteria: un traguardo di tutto rispetto se si considerano le prestazioni dell’auto, che è in grado di coprire lo 0-100 in meno di 6 secondi.

Yahoo Tech - Hidden design details that will make you want Tesla’s Model 3 even more

Hundreds of thousands of Tesla fans have been throwing money at the company to buy its cheapest electric car yet, securing their place in line to purchase the Model 3. Many of them preordered the car even before Tesla revealed its design and specs. In the meantime, almost everything is known about the Model 3 at this point, but a new report reveals hidden design details that might make Tesla’s new Model 3 one of the best electric cars money can buy in any price range. At least, for the time being. 

Inside EVs - Tesla Model 3 Aerodynamics Explained but Exa's Digital Simulation Expert

Exa’s PowerFLOW digital simulation software is used by Tesla to design its cars. While the Exa corporation doesn’t actually see Tesla’s process, the company uses the same software to analyze the vehicles, and can provide valuable information.

In order for the Model 3 to hit its promised base price of $35,000, the battery pack will need to be smaller. This makes achieving the hopeful 215 mile range a challenge. Tesla CEO, Elon Musk said the drag target is set to be extremely low, at 0.21 Cd. This is lower than the Model S that boasts 0.24.

JALOPNIK - Here's How Tesla Is Designing The Model 3 To Be The Most Aerodynamic Car Ever Made

Shortly after the unveiling of Tesla’s Model 3 earlier this month, Elon Musktook to Twitter in a storm of information about the new car, mentioning that the target drag coefficient was 0.21. If that target makes it to production, it would make the Model 3 the most aerodynamic high-volume production car ever made. Here’s the plan to do it.

Tesla recently confirmed that the base version of the Model 3 will be able to travel over 215 miles on a single charge with a battery pack “smaller than 60 kWh”. The relatively small battery capacity makes it clear that the vehicle’s aerodynamic performance is crucial to achieving the range, much like it is for the Model S and X, even with their higher capacity battery packs.

Tesla Motors Inc (NASDAQ:TSLA) Chief Elon Musk said during the Model 3 unveiling that the $35,000 vehicle will be able to travel at least 215  miles on a fully charged battery. Earlier this week, the company’s VP of Investor Relations Jeff Evanson confirmed that the automaker will be using a battery pack of smaller than 60kWh.  

Car and Driver - Beyond the Wind Tunnel: How Automakers Are Maximizing Vehicle-Efficiency Virtually

A few years ago, when Jaguar engineers commenced work on the recently introduced XE small sedan, they took what then seemed like a risky break from normal practice. Instead of building full-size clay models to develop the XE’s exterior details in a wind tunnel, they took a chance on a technology called Computational Fluid Dynamics (CFD). This enabled faster and less expensive development using digital simulation models instead of traditional physical prototypes. And a better chance of beating the class-leading BMW 3-series aerodynamic performance.

SAE Off-Highway Engineering - Evaluating thermal design of construction vehicles

Design and evaluatin of construction equipment and vehicles constitute a very important but expensive and time-consuming part of the engineering process, due to a large number of prototype variants and low production volumes associated with each variant.

Engineers from Exa Corporation and Charles Machine Works collaborated to investigate an alternative approach to hardware testing. Because of the enormity and complexity of the vehicle design process for off-highway vehicles, the researchers limited the scope of their current study to thermal evaluation of vehicle components only.

RaceXpress - Onroak Automotive on track with new LMP2 car: Aerodynamics cruicial

Vanaf 2017 is Onroak Automotive een van de fabrikanten, die LMP2-bolides mogen leveren. Inmiddels heeft het Franse merk de eerste test van het nieuwe prototype in de windtunnel achter de rug. Tevens heeft de fabrikant de naam bekend gemaakt van de auto die volgend jaar op het circuit te bewonderen is. De nieuwe bolide krijgt de naam Ligier JS P217. Deze nieuwe auto wordt in samenwerking met EXA, waarmee Onroak Automotive ook de Ligier JS P3 heeft ontwikkeld, gemaakt. 

Sportscar 365 - Onroak Confirms 2017 LMP2 Car Name, Begins Wind Tunnel Testing

Onroak Automotive has confirmed the name of its 2017-spec LMP2 car as the Ligier JS P217, with wind tunnel testing already underway for the new-generation prototype that will debut in next year’s Rolex 24 at Daytona.

The French constructor, under the direction of Nicolas Clémençon, has started wind tunnel testing with a 40 percent scale model of the car.

It comes following the initial design and development phase, in collaboration with EXA, the same company Onroak worked with on the design of the Ligier JS P3.

Onroak Automotive, retenu comme constructeur des châssis LMP2 à partir de 2017 tout comme Dallara, Riley/Multimatic et Oreca, a fourni quelques précisions à propos de son projet.

La future LMP2 s’appellera JS P217. Les initiales JS font toujours référence à Jo Schlesser, l’ami et complice de Guy Ligier dont toutes les voitures ont porté ces initiales, P2 faisant bien sûr référence à la catégorie  et 17 pour l’année des débuts du prototype.

The first stages of development focusing on CFD computer design have been completed, creating the first visual representation of the new coupe.

Automotive World - COMMENT: In vehicle design, go with the transient flow!

SUBSCRIPTION REQUIRED:

“We’ve all experienced turbulence on an aeroplane, but back on terra firma those troublesome, swirling pockets of air can have just as great an impact on how a car moves along the road and how much fuel it uses.
And for a vehicle manufacturer, the ability to accurately simulate turbulence helps to create quieter, more fuel-efficient vehicles.”

DesignNews - Advanced CAE Pinpoints HVAC System Noise, Helping Engineers Eliminate it

In computer-aided engineering, we are seeing a vast number of advanced predictive modeling tools dedicated to solving specific engineering requirements and assisting engineers who are not experts in those disciplines. In acoustical analysis targeting noise-reduction in cars, Exa Corp. has been looking to give auto engineers tools to examine flow-induced noise sources such as greenhouse or underbody wind noise, HVAC and blower noise, and noise from within exhaust systems.

Automotive Engineer - Exa Unveils Noise Detection Software

Exa Corporation, a global innovator of simulation software for product engineering, has unveiled a Flow-Induced Noise Detection (FIND) capability for its existing aeroacoustic computational fluid dynamics simulations software Exa PowerACOUSTICS.
 
The FIND software can analyse the fluid flow of a design and rank the different noise sources in order of importance. The noise generated can also be listened to before and after design modifications, so that the impact of any proposed improvements can be aurally assessed.
