We develop, test and localize wind turbines.
Made in Germany.


TAKE A SERVICE >>> W2E also offers a wide range of additional services, independent from the wind turbine licence business: mechanical engineering, load calculation, measurement and verification, FEM and structure optimization, multi-body simulation, electrical engineering, modelling and simulation of electrical characteristics, experimental investigations of noise and vibration, safety system, turbine control software design and others ...


FEM and structural optimisation

Finite element analysis (FEA) as applied in engineering is a computational tool for performing strength analysis. To solve the problem, it subdivides a large problem into smaller, simpler parts that are called finite elements. FEA simulations provide a valuable resource as they remove multiple instances of creation and testing of physical prototypes for various situations.

At W2E FEA is applied with respect to the effective guidelines to design and optimise all relevant structural components of wind turbines, including casted parts, welded structures and composites.

To ensure realistic boundary conditions the interaction of the analysed component with the surrounding structure is generally considered. Using the software MSC.Marc all kinds of non-linear effects, such as contact interfaces, material effects and clearance can be taken into account. Special care is taken on the modelling of bolted connections and bearings, considering the internal bearing design, contact angle, operating clearance, roller and raceway profiles, load sharing between rolling elements, as well as temperature effects.

For fatigue calculation W2E has developed in-house software tools. To consider the complex stress condition in a realistic manner time series are applied and multi-axial stress approach is used.

Topology optimisation is a mathematical method that optimises material layout within a given design space with the aim to minimize the component masses. It is used at the concept level of a design process and has a wide range of applications in aerospace, mechanical, bio-chemical and civil engineering. At W2E the optimisation software TOSCA is used to reduce masses of casted parts and welded structures significantly.
