This study aims to expand the application of controllable micromechanical diagnoses and treatment within human blood vessels by designing a magnetic levitation ball system in a fluid-filled circular tube. The system enables a magnetic ball to be stably suspended along a specific path under the influence of an external magnetic field. Simulations of the system’s electromagnetic field, flow field characteristics, and mechanical state were conducted by using finite element software. The study analyzed the effects of the ball’s position, magnetic pole direction, driving current, and fluid flow rate on the forces acting on the magnetic ball. Joint simulations of the flow and magnetic fields were performed using the ANSYS Workbench platform, and a multi-objective optimization method was employed to determine the parameters for stable suspension. Experimental validation demonstrated the stable suspension of the magnetic ball in a fluid tube under an external magnetic field. The experiments revealed the relationships among the driving current, fluid flow rate, and the ball’s stable suspension position, confirming the effectiveness of the simulation method and the feasibility of controlling object positions within fluid tubes</dc:description><dc:description xml:lang="sl">Raziskave na področju uporabe mikrorobotov v medicini uvajajo inovativne metode za zdravljenje različnih bolezni. Cilj te študije je razširiti uporabo nadzorovanih mikromehanskih diagnostičnih in terapevtskih pristopov znotraj človeških krvnih žil z zasnovo sistema magnetne levitacije krogle v cevki okroglega prereza, napolnjeni s tekočino. Sistem omogoča stabilno lebdenje magnetne krogle vzdolž določene poti pod vplivom zunanjega magnetnega polja. S pomočjo programske opreme so bile po metodi končnih elementov izvedene simulacije elektromagnetnega polja, tokovnega polja in mehanskega stanja sistema. Študija podaja analizo vpliva položaja krogle, usmerjenosti magnetnih polov, električnega toka in hitrosti toka tekočine na sile, ki delujejo na magnetno kroglo. Hkratna simulacija toka in magnetnega polja je bila izvedena na platformi ANSYS Workbench, pri čemer je bila uporabljena metoda večobjektne optimizacije za določitev parametrov, ki omogočajo stabilno levitacijo. Eksperimentalna potrditev je pokazala stabilno lebdenje magnetne krogle v tekočinski cevki pod vplivom zunanjega magnetnega polja. Eksperimentalni rezultati so potrdilo povezave med električnim tokom, hitrostjo toka tekočine in stabilnim položajem krogle, kar potrjuje natančnost simulacijske metode in izvedljivost nadzora položaja objektov v cevkah s tekočino</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-YB8DHCND"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-YB8DHCND" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-YB8DHCND/fed93473-b8ef-4d67-bc8c-2868d9079a24/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-YB8DHCND/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-YB8DHCND" /></ore:Aggregation></rdf:RDF>
