A certain type of alternator has had problems with its design, primarily as a result of damaged rectifiers caused by vibrations. To identify the reason for the failure an experimental modal analysis (EMA) was performed on the rectifier. The main purpose of the experimental approach was to identify some of the design factors that shorten the lifetime of rectifiers. The basis of the dynamic analysis was frequency-response functions, measured at the rectifier. Based on the measurement data of the original and modified samples of the rectifier, some corrections were made to improve the dynamic characteristics and to extend the lifetime of the rectifier. Useful information for the development of the next generation of the alternatorćs rectifier was obtained. The applied methods can also be extended to other products</dc:description><dc:description xml:lang="sl">Alternator je predvsem zaradi vibracij in načina vpetja na motor izpostavljen velikim dinamičnim obremenitvam, kar bistveno vpliva na njegovo dobo trajanja. Tako se je na obravnavanem tipu alternatorja ta doba skrajšala predvsem zaradi odpovedi usmernikov kot posledica vibracij. Da bi prepoznali vzrok odpovedi, smo na usmerniku izvedli eksperimentalno modalno analizo (EMA). Glavni namen meritev je bil spoznati konstrukcijske dejavnike, ki vplivajo na prezgodnjo odpoved usmernika. Osnova pri vrednotenju dinamičnih lastnosti usmernika so bile izmerjene frekvenčne odzivne funkcije le-tega. Na podlagi rezultatov in analize meritev osnovne izvedbe usmernika in nekaterih njenih sprememb, so bili predlagani ukrepi, ki so izboljšali dinamične lastnosti usmernika in zmanjšali možnosti odpovedi ter podaljšali dobo trajanja izdelka. Pridobljene so bile koristne informacije za konstruiranje naslednjih generacij usmernikov, uporabljene metode pa so uporabne tudi širše, na drugih izdelkih</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-CMCWOXQN"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-CMCWOXQN" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-CMCWOXQN/914de4c3-5e67-445f-b313-7089250355be/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-CMCWOXQN/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-CMCWOXQN" /></ore:Aggregation></rdf:RDF>
