SIMULATION SOFTWARE
your manufacturing environment better, but it will help save on costs,” he said. “Doing something digitally will prove out the process, and it’s a lot easier to change things on the computer screen than it is to reconfi gure them on the shop fl oor. “Digital manufacturing thus becomes an enabler for au- tomation technology. Thanks to early feasibility studies, by testing the reach and limits of various robots for certain ap- plications, it provides a higher maturity during the decision- making process,” Ziewers said. “Simulation and validation capabilities ensure a short go-life phase, and powerful offl ine-programming functions are speeding up the daily use of robot-based applications and opens the door for getting the most out of a real factory environment.” With hundreds of installations of FastSuite, Cenit has customers including Boeing, Lockheed Martin, and Ford Motor Co. in production applications such as spray paint, laser cutting of sheet metal, and automated robotic riveting, Ziewers said. “Cycle time enhancements using real-time emulation in the virtual world before commissioning them to the shop fl oor is a
major way to improve effi ciency in any factory that has automa- tion,” he said. “Virtual factory simulation gives a company the ability to truly optimize the automation components and layout of the factory to achieve the highest effi ciency possible, while also helping to cut down on the lead time for upstart. Lengthy downtimes can also be prevented because the ability to make virtual corrections in advance is much easier to accomplish.”
Leveraging CAE Simulations More widespread use of CAE and multiphysics simula- tions is also making inroads in manufacturing, as “non- expert” users become more involved with these simulations early in design cycles that have a major effect downstream on product development and manufacturing processes. “The large majority of use is around product design,” said Barry Christenson, director of product marketing, Ansys Inc. (Canonsburg, PA). But across industry in general, there has been high growth for the company outside of its traditional users, he said. “It’s important in areas like forming for auto- motive, where you have concerns about metal thinning and stresses on a product,” Christenson said. “For a deep-draw- ing process, you’d want to go through simulations, if there’s a concern about tearing.”
Designers of cutting tools also simulate their designs with the software. “One of the problems is heat tends to destroy cutting tools,” Christenson said. A lot of CFD work is in traditional manufacturing areas, with metalcutting, metalform- ing and high-speed machinery users concerned with motion, he said. In its most recent release, Ansys 16, the company addressed areas including wave loading, analyzing the ef- fects of forces from large waves hitting oil platforms. “We’ve had signifi cant growth in pharmaceutical, and in oil & gas,” Christenson said, “where they’re studying how chemicals mix or combust, if that’s part of the process.”
