Experimental investigation of particle-tuned mass dampers on vibration damping characteristics of wind turbine tower structures

Abstract The offshore wind turbine tower structure is subjected to triple-frequency vibration caused by the rotating impeller of the generator set. By designing the particle-tuned mass dampers (PTMD) and installing them on the tower structure, we study the suppression effect of the PTMD parameters and installation position on the vibration of the wind turbine tower structure in this paper. The results show that the PTMD applied on top of the tower structure can have a better vibration-damping effect, and at the same time, the particles with large particle sizes have a better damping effect on the vibration of the tower.
