AnalySwift LLC (Logan, Utah, USA), a provider of efficient high-fidelity modeling software for aerospace and energy composites and other advanced materials, announced on April 9 that the U.S. Army’s Aeromechanics Division, part of the U.S. Army Aeroflightdynamics Directorate (AFDD), has licensed the company's VABS technology for use in helicopter rotor blade modeling and analysis.
AFDD is responsible for advancing knowledge and innovative technology in both rotorcraft aeromechanics and human-system integration in order to enhance U.S. rotorcraft competitiveness. Leader for the Loads, Vibration, and Stability Group at AFFD, Dr. Hyeonsoo Yeo, is researching “sectional properties calculated from VABS, for rotary wing structural modeling and analysis.”
“We look forward to the continued relationship between the U.S. Army and the VABS engineering software program,” said Allan Wood, president and CEO of AnalySwift. “Researchers and engineers worldwide are actively using VABS for the efficient and accurate modeling of composite beams such as helicopter rotor blades, wind turbine blades, high aspect ratio wings, composite bridges, and other slender structural components.”
According to Dr. Wenbin Yu, CTO of AnalySwift, “VABS is the only tool capable of rigorously modeling three-dimensional [3-D] slender solids with complex microstructures, such as composite beams, and we are excited for the progress of Dr. Yeo’s research. The efficient high-fidelity tools offered through AnalySwift enable companies to bring products to market more quickly and at a lower cost with the best available compromise of accuracy, efficiency, and versatility.”
The technology underlying VABS is said to save users many orders of magnitude in computing time relative to more complex and time-consuming 3-D finite element analyses (FEA), without a loss of accuracy. Engineers can now design and analyze real structures with complex microstructures due to this high-fidelity feature of VABS. For instance, structures as complex as real composite rotor blades with hundreds of layers can be easily handled by a laptop computer. A new version, VABS 3.6, was recently released, which is several times faster and capable of handling even larger models.
