Računalniška simulacija procesa globokega vleka ob upoštevanju numeričnih ali geometrijskih zavornih letev : zaključna naloga Razvojno raziskovalnega programa I. stopnje StrojništvoIvić, AljažRazvoj v avtomobilski industriji gre vedno bolj v smeri zmanjšanja emisij, večje ekonomičnosti in izboljšanja varnosti. Da bi zadostili vsem pogojem, se je pričel razvoj novih, izboljšanih ... materialov. Visokotrdnostno jeklo (HSS - High Strength Steel) in napredno visokotrdnostno jeklo (AHHS - Advanced High Strength Steel) sta materiala z izboljšanimi karakteristikami, ki pa zahtevata naprednejše metode preoblikovanja. Klasične metode za preoblikovanje standardnih jekel v tem primeru ne zadostujejo, zato je za razvoj končnega izdelka ključna uporaba računalniških simulacij. S programskim paketom AutoForm R7 smo primerjali numerični in geometrijski model vlečne zavore za proces izdelave notranjega dela B stebrička v avtomobilu. Umeščen je med prvimi in zadnjimi vrati in je ključen element pri zagotavljanju varnosti potnikov v primeru bočnega trka in prevračanja vozila. Rezultati so pokazali, da je računalniška simulacija z uporabo numeričnega modela zavor hitrejša, a iz vidika rezultatov manj zanesljiva. Računalniška simulacija z uporabo geometrijskega modela zavore, traja dalj časa, a bolj natančno popiše dejansko stanje celotnega procesa preoblikovanja.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
