Many studies on automotive mass reduction have been undertaken over the years by various steel, aluminum, magnesium, and composites consortia, all expounding the virtues of substituting a particular material. Altair has participated in studies with all these organizations over the years and has understood the strengths, limitations, and constraints of working with various materials.

 

AHSS, HSS, Al, Mg, Ti, GFRP, CFRP…

High Strength Steels, Aluminum, and Magnesium all have certain advantages in specific applications. Understanding when to exploit the unique advantages of these materials while concurrently minimizing the associated cost penalty is key in any weight reduction challenge. Read More

As noted in the 2012: Simulation’s Year of Discovery post that I wrote last December, the impact of simulation continues to reveal itself, enhancing everyday products and our daily lives. From innovations in speed and crash modeling to light-weighting vehicle, aircraft and consumer packaging designs, industries are continuing to discover new ways to use simulation technology as we move through a new year. But what does that mean for simulation in 2013? How is the definition of “everyday” being shaped by technology? Read More

Last week, the North American International Auto Show kicked off in Detroit’s newly renovated COBO Center with press and industry preview days before opening the show to the public last weekend. For me, it’s easy to see how simulation technology played a role in the impressive end results for the vehicles exhibited across the show floor. However, that might not be the first thing that comes to mind when you’re staring face-to-face with a stunning concept car.

Lightweight design, performance, fuel efficiency standards, carbon emissions and vehicle safety all will continue to be topics discussed among the many engineers, analysts, automotive enthusiasts and other show attendees. Simulation technology will be inherently present within some of the most impressive products on the show floor. Read More

2012: Simulation’s Year of Discovery

, Senior Vice President – Solver products

In 2012, a growing number of industries discovered new ways to use simulation to improve their designs, safety, performance and sustainability. While the automotive sector continued to increase its reliance on simulation to make vehicles lighter and more fuel-efficient, engineers and designers found ways that simulation could save weight, costs and lives in everything from cruise ships to airliners.

We touched on these emerging trends throughout the year, and here are the top five trend-related posts that I believe demonstrate the future of simulation in our products and our lives: Read More

The Challenge of Crashworthiness for Composite Cars

, Vice President, Marketing at solidThinking

This post was taken from Altair Enlighten and contributed by my colleague, Giuseppe Resta, Manager, Global Automotive at Altair Engineering.

It doesn’t seem so long ago that passenger safety and vehicle crashworthiness were the battleground where automakers differentiated their products. Now, as many OEMs have created product development systems that rely on a CAE-driven strategy to deliver excellent passive safety performance, it appears to have taken a backseat to miles-per-gallon. Almost every car commercial touts greater fuel efficiency and seeks to validate the manufacturer’s environmental credentials.

Both safety and gas mileage advances have been pushed by regulation and pulled by consumer demand. Now that the United States has set the 54.5 mpg Corporate Average Fuel Efficiency (CAFE) standard for 2025 and lower CO2 emissions have been mandated in Europe, we are entering a new era of increased challenge that could lead to significant change in the way cars are designed and constructed. OEMs and suppliers are reviewing every component and considering the technologies available to meet these new demanding standards, including investment in engineered plastic and carbon-fiber-reinforced plastics (CFRP) that offer high stiffness-to-weight and strength-to-weight ratios.
