Abstract

The control of the dynamic response of cantilevered thin-walled beams carrying externally mounted stores and exposed to time-dependent external excitations is addressed in this paper. Toward this goal, the adaptive materials technology is used. A control law relating the piezoelectrically induced bending moment at the beam tip with the velocity at given points of the structure is considered, and its effects upon the closed-loop dynamic response is investigated. The obtained results reveal that this control methodology can play a noticeable role toward confining the oscillations of the considered structure when exposed to blast loadings.
