20.500.12556/RUL-149409 Shranjevanje energije v večstabilnih nosilcih na osnovi preskoka sistema Energy storing in multi-stable beams on the basis of snap-through V tej diplomski nalogi je predstavljeno načrtovanje, izdelava in obnašanje absorberja mehanske energije, na osnovi preskoka sistema. Objasnjena sta tudi pojma bi-stabilnosti in preskoka sistema na danem primeru. Narejeni so bili trije absorptivni sistemi. Na osnovnem absorberju smo preučevali dogajanje in odzive enega samega preduklonjenega nosilca na aplikacijo prečne sile. Osnovni model smo razširili v 4-stopenjski progresivni absorber za namen blažitve reakcijskih sil pri trku. Na obeh modelih smo izvedli natezno-tlačne preizkuse in jih primerjali s poenostavljenimi teoretičnimi izračuni. Izdelali smo še rotacijski sistem, kot prikaz možnosti aplikacije tovrstne mehanske absorpcije v rotirajoče se strojne elemente. In this diploma thesis is presented constructing, production and behavior of absorber of mechanical energy, on the basis of snap-through. The concepts of snap-through and bi-stability are explained on given example. Three absorptive systems were produced. On the basic absorber, we studied the behavior and response of a single pre-buckled beam to the application of a transverse force. We expanded the basic model to 4-stage progressive absorber for the purpose of mitigating the reaction forces in a collision. We performed tension-compression tests on both models and compared them with simplified theoretical calculations. We also made a rotary system, as a demonstration of the possibility of applying this type of mechanical absorption to rotating machine elements. shranjevanje energije preskok sistema metamateriali večstabilni sistemi natezno-tlačni preizkus energy trapping snap-through metamaterials multi-stable systems tensile-compressive test true false false [J.
