Numerično modeliranje dinamičnega odziva sipke snovi : zaključna naloga Razvojno raziskovalnega programa I. stopnje Strojništvo
Stanonik, Simon, strojnik, 1997-
V želji po zagotovitvi večje prometne varnosti udeležencev v prometu se klasične izvozno-uvozne priključke zamenjuje z izletnimi conami. V diplomskem delu smo preverili, če in kako različna velikost ...delcev sipkega material vpliva na zaustavitev krogle pri trku z njimi. V programskem paketu LS-DYNA smo naredili numerični model, s katerim smo simulirali padanje ter zaustavljanje krogle v sipkem materialu. Simulacije smo opravili pri treh različnih velikostih delcev in treh različnih začetnih hitrostih krogle. Na podlagi tako dobljenih rezultatov smo ugotovili, da pri nižjih hitrostih velikost delcev pomembno vpliva na pot, ki jo pri zaustavljanju opravi krogla, medtem ko se s povečevanjem hitrosti krogle vpliv velikosti delcev zmanjšuje. Najboljše rezultate smo dobili z uporabo delcev, katerih premer znaša 25 mm.
