SAMTECH to Demonstrate Wind Turbine Structural Dynamics at EOW2009

By DE Editors

SAMTECH is participating in the European Offshore Wind Energy Exhibition and Conference (EOW2009), which will be held from Sept. 14-16 in Stockholm, Sweden. This event will be an opportunity for SAMTECH to demonstrate advanced Structural Dynamic analysis of Wind Turbines using the new commercial release of its engineering software platform, SAMCEF for Wind Turbines (S4WT).

The industrial engineering process of large wind turbines is a complex organization involving several teams of engineers, with complementary expertise. During the last 30 years, advanced engineering software has been developed by wind energy researchers and method engineers of wind turbine manufacturers. These software tools are applicable to various disciplines and are usually used sequentially, often requiring iteration loops.

Structural dynamics, which is implemented in S4WT, corresponds to the last phase of the engineering process, where the wind turbine design is relatively stabilized, and when accurate analyses have to be performed with a detailed high fidelity FEA virtual prototype.

This complete Wind Turbine model will allow designers to check its behavior in a selection of severe load-cases required in order to guarantee the wind turbine reliability. Structural dynamic results are structural vibration responses in the time domain, Campbell or Waterfall diagrams describing possible instabilities, eigen-frequencies, and mode shapes for different configurations. This information is useful to wind turbine program managers for comparison, and correlation with experimental information coming from physical dynamic tests.
