The next step in Wind Turbine Simulation3 APPLICATIONSThis document is the property of SAMTECH S.A.Page #This document is the property of SAMTECH S.A.SAMCEF For Wind Turbines allows the computation of more accurate dynamic loads. These loads are mostly produced by wind. They are also the result of the interactions between the components and the control system. They induce fatigue that must be accurately predicted to meet the requirements linked to certification.4Comparison between measurement and S4WT results:

E-Stops are the most damaging events for some components of a turbine and must be predicted with extreme precision. SAMCEF For Wind Turbines will assist in this.Off Shore

Waves have a major impact on the complete dynamics of the structure. In addition, an extra element must be considered: the foundation. Several designs concepts exist: a monopile, a tripod, a gravity foundation SAMCEF For Wind Turbines V3 offers the ability for specific models to take account of these factors. It makes the off shore feature just one additional step in the global process !Load cases definition compatible with IEC 61400 and GL norms for certification

The next step in Wind Turbine Simulation3 APPLICATIONSEasy extraction of ultimate/sizing loadcases for design beyond certification

This document is the property of SAMTECH S.A.Page #This document is the property of SAMTECH S.A.7An important step in the global design process is computing dynamic loads acting on components.

In order to compute them properly, one must define loadcases representing the environment that will interact with the turbine during its life cycle. These loadcases are well defined in the IEC 61400 standard. SAMCEF For Wind Turbines has been made compatible with loadcase definition in order to make certification work easier.

Certification generates the use of a large number of loadcases. Some of them are more harmful for the turbine than others. These specific loadcases are the ones which must be focused on during the design phase. In S4WT, it is easy to identify those loadcases. The design can then be enhanced around them and, once results are confirmed, the complete set are relaunched for certification. DesignMORE RELIABLEMechanical Components

The next step in Wind Turbine Simulation3 APPLICATIONSThis document is the property of SAMTECH S.A.Page #This document is the property of SAMTECH S.A.The second application available through SAMCEF For Wind Turbines is linked to Mechanical components. The design of gearboxes, yaw and pitch mechanisms benefit from the higher accuracy obtained in loads computation. It results in the production of more reliable components. The description of these components can be as detailed as necessary. New concepts can be designed and tested without limit on the complexity. These advanced models can then be imported into a global model of a turbine and the sizing loadcases can be run on the machine including the detailed models.8High speed shaft at gearbox exit: bending moment and axial mouvement during E-stop

As demonstrated in this graph, there is a clear corresponding relationship between experimental and actual results. This is linked to the amount of detail that was included in the model used for this computation. Such models can only be built using SAMCEF For Wind Turbines, taking advantage of our unique technology and our advanced understanding of the physics involved.

This document is the property of SAMTECH S.A.Page #This document is the property of SAMTECH S.A.SAMCEF For Wind Turbines also features a classical Finite Elements solver. Structural components such as bedplates, nacelle, towers or offshore foundations can be modelled as well. Just like for the mechanical ones, the design of these components takes advantage of the quality of the loads computation to produce reliable parts. They can also be included in a global model, either as a complete Finite Elements model or in a condensed version of it. The loads redistribution due to the change in design of the component can then be accurately assessed. 102 Interfaces
