Abstract
V zaključni nalogi se ukvarjamo z določanjem teoretičnega pomika različnih tipov SMA aktuatorjev v odvisnosti od temperature. V nalogi najprej predstavimo materiale z oblikovnim spominom. Sledi splošna predstavitev SMA aktuatorjev iz katere sledi raziskava. V raziskavi obravnavamo 4 izvedbe SMA aktuatorjev, ki se razlikujejo po načinu izvedbe protielementa, ki nasprotuje gibu SMA vijačne vzmeti, oz. to po končanem proženju vrne v prvotno stanje. Na koncu sledi vrednotenje rezultatov in primerjava z eksperimentalnimi rezultati iz literature.

Title:Survey on shape memory spring actuator response
Abstract:
In the final thesis we deal with the determination of the theoretical temperature-dependent offset of different types of SMA actuators. In the thesis, we first present materials with shape memory. This is followed by a general presentation of SMA actuators from which the research follows. In the research we consider 4 versions of SMA actuators, which differ in the way they implement the counter-element, which opposes the movement of the SMA helical spring, or returns it to its original state after the activation. Finally, the results are evaluated and compared with the experimental results from the literature.

Keywords:actuators, shape memory, helical springs, deformations, simulations
