dc.description.abstractShape-memory-alloy (SMA) actuated flexible structures are used in a variety of configurations in many aerospace, robotics and underwater applications. In this study, a pair of nickel-titanium (NiTi) shape-memory-alloy plates is embedded in a flexible structure. An antagonistic design with a plate geometry is selected for the NiTi SMA to achieve bidirectional flexibility. A three-point-bending test is conducted to reveal the bending strength of the NiTi plates in the martensite and austenite phases. The antagonistic NiTi SMA plates are geometrically adapted and embedded into the flexible structure, which is fabricated through additive manufacturing using thermoplastic-polyurethane (TPU) flexible filament. The stabilized actuation stages of the antagonistic NiTi SMA plates embedded in the flexible structure are examined through observation of an extended number of thermal cycles. A comparison is made by applying two different electrical-current values with a regulated high-current DC power supply. A cycling profile with a maximum, bidirectional, stabilized actuation stroke of 52 mm is obtained through 100 heating/cooling cycles for the NiTi SMA-plate-actuated flexible structure. The effects of the high and low heating/cooling cyclic periods on the stabilized actuation stroke are also investigated.
dc.description.abstractZlitine z oblikovnim spominom (SMA; angl.: Shape Memory Alloys) se kot odzivne fleksibilne strukture (aktuatorji) uporab ljajo na razli~nih podro~jih: v letalstvu, robotiki in podvodnih aplikacijah. Avtor v ~lanku predstavlja {tudijo para nikelj-titano vih plo{~ (NiTi) z oblikovnim spominom, vgrajenih v fleksibilno strukturo. Izbrali so antagonisti~en dizajn geometrije NiTi SMA plo{~, da bi dosegli dvosmerno fleksibilnost. Izvedli so trito~kovni upogibni preizkus, da bi ugotovili upogibno trdnost martenzitne in austenitne faze NiTi plo{~. NiTi SMA plo{~i so pritrdili in vgradili v fleksibilno strukturo, ki so jo izdelali s pomo~jo dodajalnega postopka (AD; angl.: additive manufacturing). Pri tem so uporabili fleksibilna vlakna iz termoplasti~nega poliuretana (TPU). Stabilna stanja odziva antagonisti~ne fleksibilne NiTi SMA strukture so opazovali pri podalj{anem {tevilu termi~nih ciklov. Izdelali so primerjavo pri dveh razli~nih jakostih toka z reguliranim napajanjem z visokim enosmernim elek tri~nim tokom. Cikli~ni profil z maksimalno dvosmerno stabiliziranim aktuacijskim sunkom velikosti 52 mm so dosegli po stotih ogrevalno-ohlajevalnih ciklih. Avtorji so prav tako raziskovali vpliv dol`ine ogrevalno-ohlajevalne dobe na stabiliziran odzivni sunek.
