7th April 2014
The latest version of HyperWorks, to be highlighted at the Aircraft Interiors Expo 2014 April 8-10 (Altair booth 6D60), represents the most advanced evolution of computer-aided engineering (CAE) technology applicable to the aerospace industry. HyperWorks provides a comprehensive suite of tools for every phase of aircraft innovation, from initial concept generation through the entire product lifecycle.
Aircraft manufacturers are using the suite for weight reduction and design with composites; modern structural modeling and automated design processes; and stress, mechanism and vulnerability simulation. Software tools in the integrated HyperWorks suite are advancing the ways in which aircraft are designed, accelerating the adoption of advanced materials, such as laminated composites, to meet industry goals of reducing the weight of components and structures for greater fuel efficiency and passenger comfort.
“While composites are a major focal point for HyperWorks and the aviation industry, our product suite offers much more,” saidShan Nageswaran, Senior Director, Altair HyperWorks for Aerospace. “From automated meshing to groundbreaking optimization tools and a wide range of easily accessed partner applications, HyperWorks is helping the aerospace industry reach new heights in time efficiency, cost reduction and quality improvement all while meeting the strictest safety and performance requirements.”
Design with Composites and Weight Reduction
For composites, HyperMesh® saves significant time with its modeling process. Composites data may be read from the computer-aided design (CAD) model, with ply shapes and parameters comprehended and effortlessly mapped onto elements. Its ply-based modeling approach is more intuitive and efficient than the conventional zone-based approach, matching the physical creation of composites more closely. HyperMesh also has the ability to convert from ply to zone-based modeling for solvers that do not natively support ply-based modeling.
One of the most widely used post-processing tools globally, HyperView® provides layer-based post-processing for composites, yielding results for both individual layers and the aggregation of layers and identifying the maximum contributing layer. The module also includes predefined criteria, including well-known industry standard composite failure theories, and allows for invoking in-house codes for further manipulation of these results.
OptiStruct® is a state-of-the-art solver with non-linear capabilities for ply-based modeling. It offers size optimization for dimensioning of structural components, as well as topology optimization to substantially reduce weight by determining the ideal material distribution. OptiStruct simplifies the complexity of composite modeling, considering hundreds of load cases simultaneously to recommend the best approach. Its three-phase methodology first employs free-size optimization to find the location for reinforcements based on the ply angle. Then, size optimization indicates the number of plies of a particular orientation that are needed. Finally, shuffling optimization defines which order is optimal for the results previously generated.
Altair will showcase these HyperWorks solutions at the Aircraft Interiors Expo 2014 in Hamburg, Germany, booth 6D60. The exhibit will also include Altair’s solution for additive manufacturing with 3D-printed aerospace components from Laser Zentrum Nord and APWorks, which were designed and optimized using OptiStruct. In addition, the 3rd Altair Composite Design Seminarwill be held at CFMS, Bristol & Bath Science Park, Bristol, United Kingdom on Wednesday the 7th of May, 2014. The agenda can be found here.
