It is expected that a larger vibrational response can be produced than for a typical resonance. Then the authors utilize this system as an energy harvester, which converts energy from vibration. The energy balance between the converted energy and the energy consumed to produce the necessary weak sinusoidal force is analyzed through numerical simulations. It is shown the proposed harvester can convert more energy than a system using a typical linear system resonance"},{"@xml:lang":"sl","#text":"V delu je predstavljen fenomen stohastične resonance v povezavi z elektro-mehanskimi nabiralci energije. Stohastična resonanca se pojavi tedaj, ko apliciramo periodično silo na bistabilen sistem, kar povzroči vibracije z velikimi amplitudami. V primerjavi s pojavom linearne resonance je pričakovati, da lahko z omenjenim pristopom dosežemo večje amplitude vibracij ter s tem boljše izkoristke nabiralcev energije. Nabiralci energije delujejo na principu transformacije vibracij iz okolja v električno energijo. Vibracijsko energijo lahko konvertiramo v električno energijo na osnovi več tipov elektromehanskih pretvornikov, ki bazirajo na elektromagnetnem, elektrostatičnem ali piezoelektričnem principu. Elektromehanski pretvorniki so tipično v obliki mehanskih resonatorjev, katerih izkoristek je največji v območju resonance. Generirana moč nabiralcev energije je tako zelo odvisna od frekvence vzbujanja. V tej smeri predstavlja enega izmed uveljavljenih pristopov za povečanje efektivnosti prenosa nabiranja energije izraba nelinearnih fenomenov sistema. V primerjavi z linearnimi sistemi se nelinearni sistemi lahko odzovejo z višjimi amplitudami v širšem frekvenčnem območju"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-WP8QCBFL","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-WP8QCBFL"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-WP8QCBFL/67b4a14a-7167-4905-9cdc-abce0b451d7f/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-WP8QCBFL/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-WP8QCBFL"}}}}
