Modeliranje in optimizacija procesov po metodi končnih elementovLamut, Martin, 1977-Metoda končnih elementov (MKE) je najbolj razširjena numerična metoda za računalniške analize fizikalnih pojavov v deformabilnih telesih. Po tej metodi razdelimo telo na končno število elementov, ki ... so enostavnih geometrijskih oblik in so med seboj povezani z vozliščnimi točkami. V tehniki preoblikovanja analiziramo pomike deformabilnih teles v vozliščnih točkah in določimo napetostnodeformacijska polja v preoblikovancu in orodjih. Postopek MKE-analize razdelimo na tri osnovne korake: 1) priprava podatkov in izdelava MKE-modela; 2) izračun po metodi končnih elementov; 3) grafična predstavitev rezultatov. Pri računalniških modelih lahko enostavno spreminjamo vplivne parametre, kar nam omogoča izračun velikega števila analiz, potrebnih za optimizacijo preoblikovalnih procesov. Za verodostojne analize poleg znanja mehanike kontinumov potrebujemo tudi termomehanske osnovne parametre, pridobljene z mehanskimi in toplotnimi laboratorijskimi preizkusi. Prikazani bodo uspešno rešeni praktični problemi z različnih področij znanosti in tehnike, še posebej v preoblikovalni industriji, strojništvu, letalski industriji, elektrotehniki, energetiki, geomehaniki, kemijskem inženirstvu in farmacevtiki.Source: Promocija študija in raziskav materialov : program in povzetki predavanj, Poslovni center Slovenijales, Dunajska 22, Ljubljana, 6. 12. 2007 (Str. 11)Type of material - conference contributionPublish date - 2007Language - slovenianCOBISS.SI-ID - 660650
