abstract

A nonlinear energy sink (NES) is characterized by its ability to passively realize targeted energy transfer as well as multimodal damping. This latter feature seems to make this device very well suited for reducing the vibration level of MDOF linear and nonlinear structures. The perspective of dealing with such primary structures requires the development of an efficient NES design procedure. This paper poses the basis of such a procedure that is applied to the vibration mitigation of a drill-string system, using the software MatCont.
