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.
Since its release in early March, the eagerly awaited latest version of Altair’s CAE suite, HyperWorks 12.0 has been making work easier, faster and simpler for designers, engineers and analysts, who rely on the suite’s new functionalities and user productivity advancements in product optimization, finite element modeling, multi-physics analysis, powertrain durability analysis, lightweight design and dozens of other new features.
In particular, HyperWorks 12.0 represents significant advancements in three capabilities: design and engineering speed, streamlining complexity and improved product strength. Altair technology leaders have outlined the importance of these elements in product design and the ways that HyperWorks 12.0 can boost the performance in all three areas.

Altair has been a leader in technology and expertise to develop safer automobiles and reducing potential injury to passengers. That experience now is helping Altair create safer seating systems for airplanes. Altair recently presented some of its work for the CompositesWorld Aircraft Interiors Conference in Seattle, an event that is covered in a recent blog entry.
Altair’s optimization technology is being applied to the design of the seat frame. We all have seen the seat frames that connect the seat to the floor beams. The seat frame must withstand the static load of the passenger weight but also be able to withstand dynamic loads in case of a hard landing, extreme turbulence or a water landing. Generally, the seats are required to withstand 14-g and 16-g loads.

Success in developing the new generation of cars and trucks has demanded advancements in many arenas, including powertrains, fuels, materials, manufacturing methods and design. Computer-aided engineering tools from Altair have advanced as well allowing design engineers to improve vehicle efficiency and performance while at the same time lightening the vehicle structure. Laminate composites are beginning to play a larger part than ever in vehicle design, and Altair offers the software tools that are enabling composites to become a key material across the auto industry. Altair’s Vice President of Global Automotive, Dave Mason offers answers to some of the most important questions about Altair’s role in the use of composites for today’s vehicles.

Bus travel continues to be one of the safest modes of transportation. Global bus engineering trends focus upon quality and durability in bus design, since the typical service life of a motorcoach often exceeds 20 years and may reach 3 million km., depending on the country. Still, safety and crashworthiness remain essential elements in bus design with opportunity for improvement. Too many passengers are affected by accidents, which drive the industry to push for progress in bus safety features. Cross-country motorcoaches and school buses have been the subjects of significant attention and regulatory action, particularly in relation to rollover events.

The consumer electronics industry has a more dramatic effect on our lives today than at any other time in history, and the pace of change in this industry is mind-numbing. Never have you seen such a passionate demand and obsessive need for the latest electronics gadgets, and never have these devices occupied such a large part of our time and thoughts. They have truly become our gateway to the world.
Advancing technology has made possible many things that once seemed impossible. Looking back 20 years when the first smartphone, the Simon, was introduced by IBM, who could have imagined how much our lifestyle would be changed by smartphones? Looking forward, what will our world look like 20 years from now? It is probably beyond our imagination. Modern technology in the electronics industry moves so fast and furiously that technologies we view as advanced and bizarre today may become so ordinary that we will take them for granted as commonplace.
Consumer appetites have never been so high, as they constantly look for unique new products, while always keeping an eye on price. The pressure on electronics companies to deliver innovative products quickly at lower cost is intense, and they compete furiously to dominate the market. (more…)

Five Questions for Detlef Schneider, Senior Vice President – Solver Products, Altair
During the development process of highly engineered products, CAE can help in solving a broad range of problems and making the right decisions. This can be done at a global systems level down to a component level. In most of the cases, engineers look at single physical phenomena individually, and that’s often sufficient to proceed with good confidence in the process. However, because demands on product performance are becoming more and more challenging, while lead time is being shortened, in an increasing number of cases a product needs to be developed with a more holistic approach, considering all the relevant physical effects at the same time.

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.
