The aim of the project is to develop a new type of vibration damper that can be used to significantly improve the dynamic behaviour of slender, tower-like structures with comparatively little effort. Wismar University of Applied Sciences has applied for a patent for this fluid-particle vibration damper. The idea on which this patent is based is to be further developed into a product so that the marketing opportunities increase significantly and the university can assert its exploitation rights.
The focus of the further development of the slosh absorber is the precise adjustability of the degree of damping and the avoidance of non-linear behaviour due to breaking waves. The solution consists of floating pellets on the surface of the fluid, which extract energy from the system through friction. The optimal degree of damping can be precisely configured via the quantity and size of the pellets. The linear movement of the fluid is forced by an additional light, buoyant plate above the pellets. Higher sloshing eigenmodes of the fluids can thus be suppressed.
