General information
- Short Summary
- A German university developed a device that is particularly advantageous for the transportation and assembly of wind turbines. Vortex-induced vibrations are significantly reduced or avoided. In principle, the device can be used for all cylindrical structures (e.g. pillars) that need to be protected from vortex-induced vibrations. The university offers a license agreement as well as a technological cooperation.
- Full Description
-
Air flow around blunt bodies (structure) creates vortex shedding in their wake. This applies forces perpendicular to the direction of flow, causing vibration in the bodies. If the structure’s natural frequency is close to the vortex shedding frequency, the resulting resonance can greatly reduce structure service life.
To reduce this vibration and eliminate the service life impairment during transport and erection of wind turbine towers, a German university has developed a modularly attachable apparatus (fin plate). Damage to the tower surface is to be avoided and there should be no stress concentration. The space requirement should be low. The fin plate consists of two horizontal circular rings to which small plates with sharp edges are attached. The two-part structure allows it to be attached to the tower from two sides. This makes assembly and disassembly easy.
The function principle of the “fin plate” invention has been analyzed experimentally at model scale, showing that vibration amplitude reduction perpendicular to flow is reduced by up to 96% and in the flow direction by up to 45%.
The university offers a license agreement to companies involved in wind power and cylindrical components. If there is a need for further refinement of the technology, the university is also available for technological co-operation. - Advantages and Innovations
