Tuned rollingball dampers for vibration control in wind
Oct 14, 2013#0183;#32;A passive tunedmass damper (TMD) is a very efficient solution for vibration control in structures subjected to wind excitations. In this study, a tuned rollingball damper characterized by single or multiple steel balls rolling in a spherical container is proposed to be mounted on the top of wind turbines to reduce the windinduced vibration.
