This paper describes an analytical and experimental investigation on the property of modal disparity in a vibrating structure. For a given structure, the concept of modal disparity describes its ability to generate significant ...

A strategy to remove energy from finite-dimensional elastic systems is presented. The strategy is based on the cyclic application and removal of constraints that effectively remove and restore degrees of freedom of the ...

A sequential application and removal of constraints can remove energy from vibrating systems. In this paper several optimization formulations are suggested, whereby maximum energy removal is achieved by selecting optimal ...

We investigate the use of cable tension for active vibration control in frame structures. A general formulation for this class of systems is developed using finite elements, which includes the dynamics of the structure and ...
