Software turns to wind turbine design
Samcef for Wind Turbines is a new professional solution for the design, finite element analysis and the optimisation of wind turbines, including their transmission systems.

Samcef for Wind Turbines is a vertical application addressing the numerical simulation of complex wind turbine systems.
The first release will be demonstrated at Dewek 2004 in Wilhelmshaven (20th-21st October 2004).
In the past, the mechanical design of wind turbines was mainly based on simple multi-body simulation, possibly including control loops and on separate local structural analysis using the finite element method.
Samcef for Wind Turbines offers now an innovative solution based on the integration into a unified modelling environment of complementary disciplines like nonlinear FEM technologies for composite blades and structures, state-of-the-art gearbox modelling capabilities, generator models, servomechanisms and turbine controllers.
Samcef for Wind Turbines enables users to easily and quickly create a complete model of the wind turbine within the unique Samcef field environment, based on CAD geometries that can be imported from well known commercial CAD systems.
Users can also import existing FE models direct from external FEA packages (Nastran, Ansys etc).
Samcef for Wind Turbines provides engineers with a very easy access to detailed linear or nonlinear analyses of all relevant wind turbine components (such as gearboxes, blades and generators).
It includes advanced modelling capabilities for most usual gearbox designs (planetary stages, helical parallel stages etc).
Several models for synchronous and asynchronous generators are available, and these can be controlled either directly in Samcef or alternatively through digital control boxes imported from external functional simulation tools like Matlab Simulink.
Samcef for Wind Turbines analysis results can be blades deformed geometry, mode shapes, kinematical modes, strains, stresses in any structural component but also time evolution of gear or bearing forces, shaft torques etc.
Moreover, Samcef for Wind Turbines is also designed to be used in combination with the Boss quattro optimisation platform to produce the optimal design of the complete wind turbine system or just for specific components.
"The wind turbine sector is more and more demanding for a precise, complete and integrated CAD based simulation environment coupling mechanisms, structures and control/command aspects, because the physical dynamic behaviour of wind turbines cannot be described properly with too simple approaches", explains Andreas Heege, Manager of Samtech Iberica.
"Samcef for Wind Turbines is the first solution able to predict precisely the transient dynamic response of the wind turbine in even most unsteady operation conditions, while giving access under the same environment to classical design methods like rigid/flexible multibody simulation and linear/nonlinear FE analysis".
