SAMTECH to demonstrate S4WT V1.1 at EWEC 2008 in Brussels
 SAMTECH, the European specialist in Computer Aided Engineering
software and advanced Finite Element Analysis technology, launches
the commercial release 1.1 of SAMCEF for Wind Turbines (S4WT),
dedicated to wind turbines design and verification in dynamic
conditions. S4WT V1.1 will be demonstrated at EWEC 2008 in Brussels
(March 31st to April 3rd, 2008).
Presented for the first time at the preview conference organized by
SAMTECH the 28th of November 2007 in Hamburg on the topic
“Wind Turbine dynamic loads prediction for
certification”, the new professional product S4WT is now
available for industrial use by the Wind Energy market. “S4WT
V1.1 provides users with an open desktop which allows to edit
pre-defined wind turbine validated models, launch pre-defined
computation schemes (transient responses, modal analyses, fatigue
analyses, dynamic load amplification analyses …) and perform
specific post-processing (Campbell, Waterfalls diagrams …)
in order to analyze the wind turbine flexible dynamic behavior and
resonances”, says Andreas Heege, Head of SAMTECH Iberica, the
wind turbine centre of expertise of SAMTECH Group.
S4WT also allows the introduction of local detailed FEA models for
some selected parts of the wind turbine. This capability is
completely unique and 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 specialized computation software
for the whole wind turbine simulation (at concept level) or for
wind turbine components detailed analysis (blades, gearbox,
bearings, tower, control …) 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. 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”
explains Eric Carnoy, SAMTECH CEO. “In order to help avoiding
these dramatic and expensive consequences, SAMTECH has developed
S4WT, providing to wind industry advanced easy-to-use design &
verification software tools to wind energy sector allowing to solve
these difficult problems.”
In the immediate future, SAMTECH will take part as exhibitor (booth
N° 7A740) at the European Wind Energy Conference 2008 that will
be held in Brussels from March 31st to April 3rd, 2008. EWEC 2008
will be an effective opportunity to demonstrate the advanced
capabilities of SAMCEF for Wind Turbines (S4WT V1.1), innovative
professional engineering software dedicated to wind turbine design
taking advantage of cutting edge modeling technology.
