zaključna naloga Univerzitetnega študijskega programa I. stopnje Strojništvo - Razvojno raziskovalni program
Abstract
V zaključni nalogi je raziskovana efektivnost udarnega dušilca, ki predstavlja alternativno metodo za vnašanje dušenja v dinamski sistem. Najprej sta bila zasnovana in izdelana osnovna struktura ter udarni dušilec, nato pa smo postavili eksperiment na elektrodinamičnem stresalniku. Spremljali smo vpliv masnega razmerja na razmernik dušenja pri vzbujanju s sinusnim signalom ter vpliv masnega razmerja in uporabe različnih materialov stene votline na razmernik dušenja pri različnih nivojih vzbujanja z naključnim signalom. Rezultati vzbujanja s sinusnim signalom kažejo, da večje masno razmerje poveča razmernik dušenja, rezultati vzbujanja z naključnim signalom pa poudarjajo pomen izbire materiala stene.

Secondary title: |
Vibration absorption with an impact damper |
Secondary abstract: |
This thesis explores the effectiveness of an impact damper, which represents an alternative method for introducing damping into a dynamic system. First, the primary structure and the impact damper were designed and fabricated, followed by setting up the experiment on an electrodynamic shaker. We examined the influence of mass ratio on the damping ratio under sinusoidal excitation and the effects of mass ratio and various cavity wall materials on the damping ratio at different levels of excitation with random signals. Results from sinusoidal excitation indicate that a higher mass ratio increases the damping ratio, while results from random excitation underscore the significance of cavity wall material selection. |
