Uspešnost procesa podstrukturiranja je pogojena s točnostjo in konsistentnostjo identificiranih dinamskih lastnosti na povezovalnem območju. Ta vidik je pri eksperimentalnem vrednotenju problematičen zaradi neizogibnih pogreškov pri izvedbi eksperimentalne modalne analize. Posledično ni mogoče vzpostaviti ustreznih povezovalnih pogojev med podstrukturami, kar je ključen korak procesa podstrukturiranja. V raziskovalnem delu predstavljeno problematiko obravnavamo na različnih področjih. Prvo področje zajema postopek pridobitve eksperimentalnih modalnih modelov, na katerem razvijemo metodo hibridne modalne identifikacije. Namenjena je reševanju problematike zaznavanja dinamskega odziva v bližini vozlov lastnih oblik. Drugo področje obravnava vzpostavitev povezav med podstrukturami, na katerem predstavimo nov pristop k zapisu šibkih povezovalnih pogojev. Gre za projekcijsko metodo, namenjeno generaciji in oceni števila dominantnih neodvisnih povezovalnih enačb. Tretje področje obravnava tematiko hibridnega modeliranja z ekvivalentnimi modeli. Na tem področju, na osnovi izvirne interpretacije uveljavljenih metod, razvijemo novo razširitveno metodo v modalni domeni. V zadnjem delu predstavimo aplikacijo podstrukturiranja z eksperimentalnimi modeli, pridobljenimi z brezdotičnimi metodami za zajem dinamskega odziva</dc:description><dc:description xml:lang="sl">This doctoral thesis addresses the problem of flexible interface characterization for the needs of dynamic substructuring with experimental models. The reliability of the substructuring process is conditioned by the accuracy and consistency of the identified dynamic properties at the contact area. This aspect is problematic in the experimental evaluation due to the unavoidable errors of experimental modal analysis. As a result, it is not possible to establish appropriate constraint conditions between substructures, which is a crucial step in the substructuring process. In our research, the interface problem in experimental substructuring is addressed in different fields. The first part represents the process of obtaining experimental modal models, where a hybrid modal identification method is developed. The proposed identification approach addresses the problem of near-to-node sensor placement in experimental modal analysis. In the second part, different formulations of constraint conditions between substructures are considered. A new constraint weakening approach is proposed to generate and estimate the number of dominant independent constraints. The third part covers the topic of hybrid modeling with equivalent models. Based on the original interpretation of the established methods, a new expansion method is developed in the modal domain. The last part presents an application of the substructuring process with experimental models, obtained by non-contact response measurement methods</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">visokošolska dela</dc:type><dc:type xml:lang="en">theses and dissertations</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q1266946" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-LX6MC6ON"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-LX6MC6ON" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-LX6MC6ON/6ef1123b342c-2a08e6e6b8639b--45a-ded/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-LX6MC6ON/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-LX6MC6ON" /></ore:Aggregation></rdf:RDF>
