Upgrade for wind turbine design package
Advanced easy-to-use design and verification software tools help the wind energy sector to solve difficult problems.
Samtech has developed a new version of its Samcef for Wind Turbines (S4WT) package, which it will demonstrate at EWEC 2008 in Brussels (31st March to 3rd April 2008) "S4WT V1.1 provides users with an open desktop which allows to edit predefined wind turbine validated models, launch predefined computation schemes (transient responses, modal analyses, fatigue analyses, dynamic load amplification analyses etc) and perform specific post-processing (Campbell, waterfalls diagrams etc) in order to analyse the wind turbine flexible dynamic behaviour and resonances", says Andreas Heege, Head of Samtech Iberica, the wind turbine centre of expertise of Samtech Group

Package optimised for machine tool design
Samtech has released the first industrial version of Samcef for Machine Tools, its professional solution for the design, analysis and optimisation of machine tools.
S4WT also allows the introduction of local detailed FEA models for some selected parts of the wind turbine.
This capability is reckoned to be unique, and is a first step in the connection between global flexible mechanisms simulation and local stress analyses using finite element analysis.
Thanks to its general data model and its plug-in technique available in the general purpose open CAE framework Caesam on which it is based, S4WT is also the appropriate basis for the future integration of any pre-existing specialised computation software for the whole wind turbine simulation (at concept level) or for wind turbine components detailed analysis (blades, gearbox, bearings, tower, control etc) using analytical or numerical techniques (MBS or FEA for example).
"Building a highly reliable wind turbine is a big challenge, since wind turbines are large flexible articulated structures submitted to aerodynamic transient excitations", explains Eric Carnoy, Samtech CEO.
"We just have to open economical newspapers to read how wind turbine manufacturers are facing with huge problems due to dynamic loading and fatigue, like failure of transmission gear pinions, failure of bearings, blade fracture, tower buckling".
"Manufacturers meet these problems often and often and insurance companies become reluctant in supporting financially these energy production stops".
"In order to help avoiding these dramatic and expensive consequences, Samtech has developed S4WT, providing to wind industry advanced easy-to-use design and verification software tools to wind energy sector allowing to solve these difficult problems".
