Abstract EN
This paper considers the RL shunt damping of rotationally periodic structures with an array of regularly spaced piezoelectric patches.
The technique is targeted to the damping of a specific mode with n nodal diameters.
For this particular case, one can take advantage of the shape of the targeted mode to organize the piezoelectric patches as a modal filter (in parallel loops) which reduces the demand on the inductors of the tuned inductive shunt.
In the case of a perfectly rotationally periodic structure, it is possible to organize 4n piezoelectric transducers (PZT patches) in two parallel loops of 2n patches each.
In this way, the demand on the inductors is reduced by 4n2 as compared to independent loops, which may allow a fully passive integration of the RL shunt in a turbomachinery application.
The method is first illustrated experimentally on a circular plate; it is then applied to a prototype of an industrial bladed drum.
The influence of blade mistuning is investigated.
