Abstrakt: In this paper, an approach is presented that allows damping of vibrations at several frequencies included into a continuous frequency range. The approach is based on a combination of two independent techniques. One technique is aimed at the selection of the optimal location of the piezoelectric element for its highest performance at several frequencies from some specified frequency range. The other one is developed for determining the parameters of the shunting RL-circuit which provide damping of vibrations at several frequencies for the corresponding location of the piezoelectric element. The applicability of the proposed approach is demonstrated using a shell structure in the form of a semi-cylinder with a piezoelectric element attached to its surface and shunted with a single resonant RL-circuit.
