Abstrakt CZ: Příspěvek se zabývá limitními provozními stavy aktuátoru pracujících na principu termoelasticity, jež jsou ovlivněny geometrií zařízení, použitými materiály a parametry budicího proudu. Úloha je řešena jako sdružený problém. Pro ilustraci je navrženou metodou spočten typický příklad.
Abstrakt EN: Actuators working on the principle of thermoelasticity exhibit specific properties (particularly very high forces at small shifts) and may be used, for example, as prospective fixing elements in numerous industrial applications. But huge mechanical strains and stresses in their active structural parts may lead to irreversible damage or even destruction of the whole device. The paper deals with the limit operation regimes of a typical actuator of this kind that are influenced by geometry of the device, materials and parameters of the field current. The task is solved as a coupled problem where the electromagnetic field is supposed to be independent of the fields of the temperature and mechanical strains and stresses. On the other hand, the two last fields are solved simultaneously. The methodology is illustrated on a typical example.
