Abstract

The Virtual Turning Damper (VTD) stemming from Turning Mass Damper (TMD) is introduced. The mathematical model of VTD is deduced from TMD firstly. The parameters of VTD are designed by the placement of poles and zeros and explained with an example. The influence of non-pure modal measurement on VTDk and modal control spillover are analyzed. The method about optimal placement of a VTDk is presented. The multi-VTD is studied. VTD can be designed by use of the commercial control software. The realization of VTD is more softness than MTD. It is easy to control the wide-band vibration with multi-VTD.
