Korea Institute of Energy Research Selects VABS for Composite Blade Modelling

17 March 2015

AnalySwift's VABS program has been chosen by the Korea Institute of Energy Research (KIER) for rigorous modelling of composite wind turbine blades.

“We are very pleased to be selected by KIER for their composite blade design and analysis needs. VABS is uniquely suited to address the challenges in modeling complex composite blades. Preliminary design work that previously took months can now be accomplished in weeks, reducing uncertainty, costs, and time-to-market. For instance, a real composite blade that would typically take over 3 hours to analyse using 3D finite element analysis (FEA) can now be done in less than 40 seconds using VABS, without a loss of accuracy. Even with hundreds of layers, all this is done on a laptop computer, without the need for heavy computing resources” said Allan Wood, President and CEO of AnalySwift.

Dr. Wenbin Yu, CTO of AnalySwift says “VABS is quickly becoming the tool of choice for researchers and engineers worldwide modelling composite slender structures such as wind turbine blades, helicopter rotor blades, high aspect ratio wings, and other slender structural components. VABS is the only tool capable of rigorously decoupling an original 3D slender solid with complex microstructure into a simple engineering beam model. This is thanks to the unique mathematical approach underlying VABS, as well as development spanning over 15 years.”

According to AnalySwift, economies of scale for larger wind turbines has led to a trend of larger blades and the increased use of composite materials, which further complicates the engineering work. However, the VABS software program enables customers to reliably model wind turbine behaviour before any substantial cost is committed to building prototypes and testing. VABS is especially valuable to engineers early in the design process due to its ability to quickly deliver the complete set of both multi-physical properties and multiphysical 3D fields. Because it is highly optimised for efficiency, ply-level details are easily included in the analysis.
