A study of appropriate arrangement of thermoelastic actuator

Abstract

The actuators working on the principle of thermoelasticity belong to novel elements of this kind that are characterized by very high forces acting at relatively low shifts of the dilatation element. The paper analyses their operation properties in the dependence of selected geometrical parameters of the device and also the amplitude and frequency of the field current. The task is solved as a coupled electromagnetic-thermoelastic problem. The theoretical considerations are illustrated on an example whose results are discussed.
