摘要

The goal of this paper is to present an impulse release of strain energy strategy for damping of free vibration in adaptive structures (equipped with actively controlled dissipaters). The concept can be applied to skeletal structures as well as to two-layer beams or plates, where stored strain energy available for dissipation through eventual ,,ddamination effect" is relatively high.rnFor simplicity of presentation, the concept is demonstrated on ideal quasi-static model of dissipative effect in the first section and then, fully dynamic simulation of the adaptive structure behaviour is demonstrated on numerical examples in the second section.rnThe main concept has been already formulated and discussed on the classical elastic beam model (Ref.l)and a particular technical application has been proposed (Ref.2). Similar approach to the problem of strain energy dissipation with use of controllable rotational dissipaters in joints of skeletal structures has been also proposed recently (Ref.3).
