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.
