Merjenje notranje osne sile v nosilcu z uporabo merilnih lističev : zaključna naloga Razvojno raziskovalnega programa I. stopnje StrojništvoVrtač, TimV zaključni nalogi smo preučevali možnost merjenja notranjih sil in momentov v nosilcu. Pri merjenju nateznih deformacij se pojavi težava v primeru čiste osne obremenitve, saj so rezultirajoče ... deformacije razmeroma majhne. Za namen merjenja tovrstnih deformacij smo preučili uporabo različnih merilnih lističev. Poleg tega smo raziskali možnosti modifikacije prereza nosilca na mestu merjenja deformacij, preko katerih bi povečali deformacije sistema. Na podlagi teoretičnih izračunov deformacij in upoštevanja omejitev, ki so se pri posameznih rešitvah pojavile, smo z vidika ustreznosti ovrednotili različne koncepte merjenja. Za najprimernejšo se je izkazala metoda določanja notranje osne sile na osnovi meritev upogibnih deformacij namensko izdelanega merilnega elementa, ki se ga namesti na želeno mesto merjenja osne sile. Razvoj namensko izdelanega merilnega elementa je temeljil na analitičnih in numeričnih preračunih deformacij, sama validacija koncepta pa je bila izvedena na osnovi izmerjenih deformacij na laboratorijskem nosilcu.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [T.
