Abstract. Actuators with elements made from alloys with shape memory have been developed and explored. These actuators may be used in small compressors, in damping systems and in pneumo-vibrotransducers. Some experimental dependencies of mechanical and other physical characteristics of these actuators have been obtained. Equation systems describing the motion of the actuators have been studied. Some characteristics of vibrotransducers, properties and technical parameters of damper were analysed. Examples of technical soliutions are presented and concrete application areas for these actuators in technological processes are indicated.

Pneumatic vibroexciters which consist of smart materials’ structural elements and are operating under autovibration regime were designed. The chamber of vibroexciter actuator with changeable capacity for flowing pressured air made of shape memory alloy (SMA) were presented. Mechanical characteristics of such type vibroactuator were estimated: maximum deformation of structural element with SMA, possible force of martensitic transformation. The result of the research allows to design functional adaptive pneumatic vibroexciters with are suitable for the different purposes of technological processes.
