Simulacija streljanja s fračo iz hiperelastičnega materiala : zaključna naloga Univerzitetnega študijskega programa I. stopnje Strojništvo - Razvojno raziskovalni programBedić, ŽigaCilj naloge je zasnovati preprosto simulacijo streljanja s fračo, ki odraža obnašanje frače in izstrelka med strelom. Frača ima dva rogla, elastična nit pa je narejena iz gumijastega materiala, ki ga ... je možno dobro opisati s hiperelastičnim materialnim modelom. Pred obravnavo gibanja izstrelka smo s pomočjo nateznega preizkusa določili potrebne materialne lastnosti elastične niti. Za teoretično analizo mehanske karakteristike elastike smo uporabili dva reološka hiperelastična modela materiala, Mooney-Rivlinovega in Neo-Hookeovega. S primerjavo teoretično dobljene krivulje z eksperimentalno smo določili materialne parametre elastike, s pomočjo katerih smo nato izračunali količino potencialne energije, ki se med napenjanjem frače shrani v njej. Ob predpostavki, da se vsa potencialna energija, shranjena v frači med strelom pretvori v kinetično energijo, smo izračunali izstrelitveno hitrost in nato preko preproste simulacije analizirali kakšen vpliv na gibanje izstrelka imajo izstrelitvena hitrost, naklonski kot izstrelitve in aerodinamični upor. Prišli smo do ugotovitve, da izbira hiperelastičnega materialnega modela vpliva na količino energije, ki se med napenjanjem shrani v frači, kar posledično vpliva na izstrelitveno hitrost in gibanje izstrelka.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [Ž.
