Reducing Costs With Virtual Design and Testing of Wind Turbine Components

As the size of wind turbines increases, the design of blades, control systems, and supporting structures becomes more complex because stress and other factors that cause failure are on a bigger scale. This creates greater engineering challenges as well as those in sourcing, manufacture, logistics, installation and maintenance. New designs need to be quickly tested for fatigue and twisting under expected operating conditions on- or offshore. Finite Element Analysis (FE) is used to test structural integrity of potential designs. Virtual and physical wind tunnel testing is also conducted. Tests on foundations, the interaction of components with each other as well as testing the entire fabrication in virtual operating situations is performed. This needs to be done fast so that designs can be certified and put to use quickly as possible. It is neither economical nor practical t...
