الوصف: V delu je predstavljena uporaba 3D natisnjenega metamateriala za dušenje nihanja v dinamičnih sistemih. Preko bazne celice so obravnavane lastnosti neskončnega 1D periodičnega metamateriala. S pravilno zasnovo je metamaterial sposoben tvoriti pasovno zavrnitveni filter v željenem frekvenčnem območju. Tega smo določili z uporabo metode končnih elementov, katere rezultat so bile disperzijske krivulje, ki smo jih dobili preko inverznega pristopa. Preračunan koncept metamateriala smo nato izdelali s pomočjo FFF tehnike 3D tiska. Preko teorije nehomogenega širjenja valovanja smo nato eksperimentalno vrednotili preračunane disperzijske krivulje. Rezultati so pokazali, da je metamaterial sposoben tvoriti pasovno zavrnitveni filter v željenem frekvenčnem območju. In this work, the use of 3D printed metamaterial for damping vibration in dynamic systems is presented. Through analysis of the unit cell, properties of infinite 1D periodic metamaterial are formed. With the proper design, the metamaterial is able to form a bandgap filter in the desired frequency range. This was determined using the finite element method, the result of which were dispersion curves obtained via the inverse approach. The calculated concept of the metamaterial was then fabricated using the FFF 3D printing technique. The dispersion curves calculated were then experimentally evaluated using the theory of inhomogeneous wave propagation. The results showed that the metamaterial is able to form a bandgap filter in the desired frequency range.
