Efficient High-Fidelity Design and Optimization of Composite Blades Using VABS

This webinar will demonstrate how one can use VABS through Altair APA to conduct efficient and high-fidelity design and optimization of composite blades. Realistic examples will be used to demonstrate that VABS can be used to match specific blade properties. Linking VABS with a multibody dynamics simulation code, it can also be used to optimize dynamic performances of rotating blades. Significant weight reduction can be achieved by making use of composites in comparison to the benchmark. The versatile modeling capability of VABS can be used to model realistic blades along with needed manufacturing constraints. All the complex three-dimensional stress and strain states within each layer of the composites can be accurately captured using VABS during the rapid optimization process.

VABS: Modeling Composite Beam-like Structures with 3D FEA Fidelity

Variational asymptotic beam section (VABS) is a unique technology continuously funded by the US Army since 1988 and it has become a tool of choice in the helicopter and wind turbine industries for modeling composite rotor blades. With analysis of a finite element meshed cross section, VABS can compute the best set of beam properties for 1D beam analysis and also accurately recover 3D stress/strain distribution over the cross section. VABS has been integrated with HyperWorks and OptiStruct for Altair users to take advantage of this powerful technology for better design and analysis of composite beam-like structures.  The recording of the presentation by Dr. Wenbin Yu, CTO of AnalySwift, is almost 20 minutes long, and was originally presented at the 2020 ATCx Composites.
