20.500.12556/RUL-149395 Akustične lastnosti prilagodljivih Miura origami struktur Acoustic properties of adaptive Miura origami structure Klasični materiali, ki se uporabljajo v akustiki, so fiksni in se njihove lastnosti ne spreminjajo, zato se v zaključni nalogi osredotočimo na glavni cilj, ki je ugotoviti ali so akustične lastnosti povezane s spreminjanjem geometrije Miura origami vzorca, ki prinaša novo področje materialov s spremenljivo in prilagodljivo geometrijo. Tekom naloge smo uporabili eksperimentalno metodo, s pomočjo katere smo pokazali, da se s spreminjanjem strukture spreminjajo tudi akustične lastnosti, ki pa nimajo trivialne povezave s Fourierjevo transformacijo površine in s frekvenco Helmholtzovega resonatorja. The classical materials used in acoustics are fixed and their properties do not change. Therefore, in the final thesis, we focus on the main objective, which is to determine whether acoustic properties are linked to the variation of the geometry of the Miura origami pattern, introducing a new field of materials with variable and adaptable geometry. Throughout the study, we employed an experimental method, through which we demonstrated that by altering the structure, acoustic properties also change. However, these changes do not have a trivial connection with the Fourier transform of the surface or the frequency of the Helmholtz resonator. origami akustične lastnosti koeficient zvočne absorpcije odmevnica Fourierjeva transformacija površine Helmholtzov resonator origami acoustic properties sound absorption coefficient reverberation chamber Fourier transform of the surface Helmholtz resonator true false false [E.
