Apparently, the engineers who designed the rotating amphitheater at the Hoover Dam took their proximity to Las Vegas too seriously. They took a gamble and designed the turntable, which holds 450 people, without using finite element analysis. Bad idea. Soon after the amphitheater opened, the turntable broke down. Engineering consultant David Dearth got a U.S. Department of Interior contract to determine the cause of the failure. He did use FEA, specifically MSC.visualNastran for Windows. Finding: Use stronger steel and bigger axle.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
