Wind energy

Wind energy plays an important role in increasing the percentage of renewable energies in the future energy mix. Wind energy is considered particularly future-proof since it is available worldwide on a permanent basis. Researchers have come to the conclusion that the world’s energy requirements could be covered by wind without significant climate control. Modern wind turbines are an emerging technology which is still being further developed with the aid of research and development. The aim is to achieve greater cost efficiency. Modern calculation methods and computer simulation help to achieve this goal at a low price in a short space of time.

Our core expertise for the wind energy sector

Structure simulation
Structure simulation evaluates the strength, stability and service life of components under mechanical or thermal boundary conditions. It allows precise analysis of stresses, for example, which can then be optimised in a targeted way.

Computational fluid dynamics
Numerical computational fluid dynamics (CFD) calculates phenomena which occur as gases and fluids flow over surfaces. Examples of uses in the wind power industry include wind loads on propellers and towers, optimisation of gear hydraulics.

NVH (Noise, Vibration, Harshness)
NVH calculations allow conclusions to be drawn on how to implement improvements to acoustics. A typical application for such calculations is their use to help reduce noise from the flaps in the blades.

The use of different mathematical calculation methods identifies optimisation potential for individual components or component groups regarding their weight or mechanical properties. Analysis results are incorporated into the development process once or as a continuous improvement activity. Typical fields of application in the wind power industry include structural component optimisation, multi-physics problems and stability studies.

Multi-body system simulation
Multi-body system simulation is primarily used for rigid body calculation and kinematic simulation of articulated joints and drives of all types. The calculation speed of multi-body system simulation enables complex modules such as entire assemblies to be easily mapped and integrated into control circuits.

System simulation
System simulation is used to examine highly complex overall systems in which many sub-systems interact. Mapping and simulating such a system is a supreme discipline: the physical properties of all components and sub-systems which are interconnected with each other and exert influence on one another must be described in a mathematically correct way and their behaviour evaluated. It is essential not to lose sight of the overall system as a sum of all parts for all details. TECOSIM has specialised in 1D simulation.

Coupled or multi-physics simulation
Sometimes it is simply not sufficient to examine the physical properties of components in isolation. Whenever several physical phenomena are simulated regarding their interaction, this is referred to as multi-physics simulation. Findings established in this way often present a truer picture than separate studies of individual phenomena. Multi-physics simulations play an increasingly important role in all stages of a product’s life cycle, from the analysis of new material properties, their mapping in virtual material models and parameters, through to production process simulation and calculation of product resistance under the effect of flow.
