Barši Palmić, Tibor (author), Slavič, Janko (mentor)

Cilj doktorske naloge je razviti metode za 3D tisk in karakterizacijo dinamskega dielektričnega aktuatorja ter zasnovati elektromehanski model. Metoda 3D tiska vključuje konstrukcijo aktuatorja, razvoj programa za generiranje g-kode in strategijo 3D tiska. Natisnjeni aktuatorji so elektromehansko karakterizirani v širokem frekvenčnem področju (do 5~kHz), kar omogoči raziskavo njihovega dinamskega delovanja. Z razvojem analitičnega elektromehanskega modela smo lahko izpeljali konstrukcijske principe za prilagajanje dinamskih lastnosti 3D-natisnjenih aktuatorjev. Rezultat tega dela so metode, ki omogočajo 3D tisk individualiziranega dinamskega dielektričnega aktuatorja, ki ga lahko s pomočjo elektromehanskega modela prilagodimo za specifične potrebe in z metodami karakterizacije potrdimo njegovo delovanje.

Abstract

The aim of the PhD thesis is to develop methods for 3D printing and characterization of dynamic dielectric actuators and to design an electromechanical model. The 3D printing method includes the design of the actuator, the developed g-code generation program, and the 3D-printing strategy. The actuators are electromechanically characterized in a wide frequency range (up to 5~kHz), which allows the study of their dynamic operation. By developing an analytical electromechanical model, we were able to derive design principles for tailoring the dynamic characteristics of 3D-printed actuators. The result of this work are methods that enable 3D printing of an individualized dynamic dielectric actuator that can be adapted to specific needs using an electromechanical model, and whose operation can be confirmed using characterization methods.
