AnalySwift has partnered with Altran to release Altran’s upcoming optimisation code for the preliminary design of composite wind turbine blades.

AnalySwift explains it’s VABS and PreVABS software will play a key role in combination with other optimisation and mathematical tools developed in-house by Altran as part of their new optimisation code. Altran’s code, the company says, is a generalistic tool, and is based on aerodynamic and structural calculations. Still under development, it will include an optimisation loop to modify structural pre-design.

The code will address aerodynamics, structural modelling, and optimisation of emerging wind turbine blades. AnalySwift’s VABS and PreVABS software will interface with and complement Altran’s code. VABS, now  in version 3.7, to enable the rigorous modelling of complex composite slender structures, or “beams”, such as wind turbine blades, helicopter rotor blades, propellers, wing sections, and bridges.

PreVABS is a design-driven pre-processor to VABS. “AnalySwift is excited about the continued relationship with Altran, a leader in high-tech engineering consulting,” said Allan Wood, President and CEO of AnalySwift. “Researchers and engineers worldwide are actively using VABS for the efficient and accurate modelling of composite slender structures. In addition to its powerful analysis capabilities, VABS is also recognised for helping organisations get products getting to market more quickly, at a lower cost, and with a higher confidence in quality.” 

“Due to its versatility, VABScan model beams of any shape and a wide variety of materials,” commented Dr. Wenbin Yu, CTO of AnalySwift. “In fact,VABS can deal not only with arbitrary lay-ups, but also with isotropic, orthotropic, and general anisotropic materials. As such, VABS delivers the best available combination of accuracy, efficiency, and versatility.”

The company states that the unique technology underlying VABS renders it the first truly efficient high-fidelity modelling tool for composite slender structures, saving users many orders of magnitude in computing time relative to more complex and time-consuming 3D finite element analyses (FEA), without a loss of accuracy. Instead of choosing between accuracy and efficiency; engineers can now confidently design and analyse real structures with complex microstructures. For instance, structures as complex as composite rotor blades with hundreds of layers can be easily handled by a laptop computer. Analysis time can typically be reduced from several hours to just seconds.
