The frequency response and the transient response of cantilever beams were analysed. The damping layers made from rubber or from a cork-rubber composite material were used in the investigated hybrid structure. A laser-measurement device and an accelerometerwere used for the measurement of the responses. Pareto optimization was performed using three-dimensional numerical simulations with the aim to maximize the fundamental natural frequency and the damping ratioSestavljeni kompozit iz plastike, ojačane z ogljikovimi vlakni in s plastmi za dušenje naravnih frekvenc, je bil preiskovan eksperimentalno in z numerično simulacijo. Analiziran je bil frekvenčni odgovor in prehodni odziv konzolnega nosilca. V preiskovani hibridni strukturi je bila plast za dušenje izdelana iz gume ali sestavljena iz gume in plute. Za meritve odgovora je bil uporabljen laserski merilnik in merilnik pospeška. Z uporabo tridimenzionalne numerične simulacije je bila izvršena Paretova optimizacija za maksimiranje osnovne naravne frekvence in količnika dušenjaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
