The model is based on various methods and procedures that as a result provide information about the generatorćs condition, the gear in particular. The acoustical model is part of a complex system that units' different models to meet diagnostics of single stage gear wheels as precise as possible. Using the adaptive FIR filter, acoustical model enables the calculation of impulse response for different notch lengths between 0 and ac. The acoustical model consists of digital FIR filter, modified by LMS algorithm, used to calculate impulse responses in non-linear systems, the model for the calculation of any impulse response and the frequency analysis with the use of FFT for the simulation of frequency spectrums. Frequency spectrum of the simulated sound signal enables an analysis of the error that can be used for calculating the remaining service life and/or determining the control cycle of maintenance</dc:description><dc:description xml:lang="sl">Prispevek predstavlja akustični model za nadzor in diagnostiko enostopenjskih zobniških gonil. Model temelji na različnih metodah in postopkih, ki kot rezultat podajo informacijo o stanju gonila s poudarkom na zobniški dvojici. Akustični model je del zatevnega sistema, ki združuje različne modele, s ciljem omogočiti čimbolj natančno diagnostiko enostopenjskih zobniških gonil. Akustični model s pomočjo prilagodljivega FIR filtra omogoča izračun impulznihodzivov za poljubno dolžino zareze v korenu zoba zobnika med 0 in ac. Akustični model vsebuje digitalni FIR filter, ki je spremenjen z LMS algoritmom in računa impulzni odziv nelinearnih sistemov, model za izračun poljubnega impulznega odziva in frekvenčno analizo, ki z uporabo FFT simulira frekvenčni spekter. Frekvenčni spekter zvoka omogoča analizo poškodbe zob zobnikov in na osnovi teh določanje preostale življenjske dobe in/ali procesa vzdrževanja</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-SLFM56RX"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-SLFM56RX" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-SLFM56RX/ce1bbb8f-f827-477d-8324-14518f632d1c/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za strojništvo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-SLFM56RX/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-SLFM56RX" /></ore:Aggregation></rdf:RDF>
