Abstract

The paper reports of an experimental and theoretical study of vibrations control in a rotating pendulum with a TiNi elastic element. The control was achieved by short periodic heat impulses synchronised with the period of vibrations. In the course of each impulse the alloy was transformed into austenite and then back to martensite after heating had been stopped. Depending on the time position of each impulse in the reference to the period of vibrations there have been obtained strong damping, sustained vibrations and growing amplitude of oscillations. Theoretical simulation of these phenomena has been grounded on a microstructural approach. All observed regimes of vibrations control have been obtained in modelling. Thus the model can correctly describe all basic effects of deformation of TiNi and that vibrations control is the direct sequence of these effects.
