NAFEMS webinar—Democratization: Expert Knowledge Capture & Reuse, Sept. 17, 11:00 am EDT. Speakers: Dr. Glen Steyer & Ravi Desai, American Axle & Manufacturing; Tory Scola, NASA Langley; Bruce Jenkins, Ora Research. Forward-thinking companies have embraced targeted, solution-focused “simulation apps” to gain measurable improvements in innovation, development time and related product quality. Leveraging this approach has allowed companies to work with dispersed departments, suppliers and partners, all while maintaining control and consistency, enforcing standards, and ensuring the validity of analysis results. This webinar will feature practical examples of automation templates and simulation apps at work, and the ROI that companies have experienced. Register here.

Taiwan began designing and developing its first satellite in 1994 in collaboration with a U.S. space systems contractor. FORMOSAT-1 was launched in January 1999 and provided service until its retirement in 2004. FORMOSAT-2 was launched later in 2004, followed by FORMOSAT-3 in 2006. In 2010, FORMOSAT-5 passed design verification and now awaits deployment. FORMOSAT-5 will carry the first optical remote sensing instrument payload completely designed and developed by Taiwan itself.
Today FORMOSAT-8 is under development. This new satellite will inherit the experience from FORMOSAT-5 and will likewise carry an optical remote sensing instrument developed by Taiwan. Opto-mechanical systems integration will be led by the country’s Instrument Technology Research Center, with participation by the Opto-Mechanical Design Analysis (OMDA) Lab supervised by Professor Yi-Cheng Chen at Taiwan’s National Central University, which is responsible for weight reduction of the mirror supporting structure. To achieve the breakthrough improvements required in structural weight, the OMDA Lab is utilizing FEA-Opt Technology’s SmartDO design optimization, system integration and process automation software.

Executive summary—Wingtip devices are intended to reduce aircraft drag through partial recovery of the tip vortex energy. Fuji Heavy Industries (FHI) used Noesis Solutions’ Optimus to automate and couple FEM and CFD simulations to identify optimized winglet design configurations offering operational and environmental benefits. Optimus realized a 1.2% reduction in aircraft takeoff weight for a typical mission profile at 1G cruise speed. It achieved this by balancing the aerodynamic benefits and weight penalties of a passenger aircraft model integrating wing reinforcement to withstand winglet induced loads. Optimus’ design of experiments (DOE) and response surface modeling (RSM) capabilities helped FHI engineers understand the impact of winglet characteristics on aircraft performance up-front. Global design optimization enabled them to reduce the aircraft’s cruise drag by 4% and its takeoff weight by 676 kilograms, while respecting the shock induced separation (SIS) airflow constraint.

NAFEMS announced an initiative to collaborate with industry thought leaders and end-user companies to develop and deliver a webinar series titled Simulation 20/20—The Next Five Years. This year-long program will offer 14 webinars aimed at advancing the understanding, usability and application of current and emerging CAE technologies and methodologies. The series will commence Thursday, August 27 with a webinar titled Democratizing CAE that will discuss how CAE analysis is being deployed to a broadening group of users throughout product development using template-based simulation applications. Register for this webinar here. Following will be three webinars based on case studies related to the democratization topic: Expert Knowledge Capture & Reuse, Usability and Accessibility.

Last week’s case study looked at how Stanley Black & Decker’s DeWALT Industrial Tools brand optimized the efficiency and user comfort of its products at the same time as their robustness and durability with Altair’s AcuSolve, HyperMesh and HyperStudy software. This week’s story is how Stanley Black & Decker chose Altair’s HyperWorks Unlimited appliance to optimize its CAE processes for power tool design. The fully managed HPC system includes unlimited license for the HyperWorks suite of solvers, design exploration, meshing and visualization products as well as the PBS Works suite for HPC workload management.
Challenge: Improving the capacity for design optimization and innovation
As a global power tool leader, Stanley Black & Decker (SBD) is constantly seeking ways to maintain a competitive edge and bring better-performing products to market faster. In particular, when it came to optimizing the hammer mechanism design for their top-selling rotary hammers, SBD engineers knew they needed a CAE-based approach. Continue reading
Development of modern electric power tools for professional applications requires simultaneous attention to two sets of product attributes: those that determine a tool’s efficiency and user comfort, and those that determine its robustness and durability. To optimize both sets of attributes together, Stanley Black & Decker Deutschland GmbH relies on computer-aided simulation using Altair’s AcuSolve CFD flow solver in combination with its HyperMorph mesh manipulation tool and HyperStudy multidisciplinary design exploration, study and optimization software. In a paper presented at the 2013 European Altair Technology Conference in Turin, Italy, the company described how these simulations were used throughout the product development cycle—from the pre-development phase, through testing near-series prototypes, and beyond to improving designs based on product-failure returns.
