Projekat

Razvoj stohastickog modela utvrdivanja elemenata vremena rada proizvodnog ciklusa i njihova optimizacija za serijsku proizvodnju u metalopreradivackoj industriji i u procesima reciklaže (MPNTR - 35017)

Sažetak

U radu je dat pregled naših prethodnih istraživanja uz dodatna unapređenja, tako da je dokazana hipoteza da putničko vozilo još uvek nije ergonomski prilagođeno čoveku u dovoljnoj meri, posebno u delu unutrašnjeg prostora za smeštaj i upotrebu nožnih komandi. U ergonomskom prilagođavanju putničkog vozila najznačajnija su tehnička i antropometrijska ograničenja. Pri samom istraživanju je u najvećoj meri korišćena metodologija operacionih istraživanja, tako da su ciljevi opisani funkcijom cilja, dok se sistem 'čovek-vozilo' optimizira uz postojanje ograničenja. U savremenim zaoštrenim ekonomskim i ekološkim zahtevima održivog razvoja u ovom radu je ostvaren cilj konstrukcije unutrašnjeg prostora standardnog putničkog vozila sa optimalnom čeonom površinom i koeficijentom otpora vazduha. Data je originalna metodologija za određivanje unutrašnjeg prostora putničkog vozila. Činjenica da postoji '0' tačka kao ishodište koordinatnog sistema sa x, y i z osom sistema čovek - vozilo, koja se može smatrati približno fiksnom, omogućila je tačnije određivanje mehaničkih i matematičkih zavisnosti u ovom sistemu. U radu je dokazano da antropomere po dužini imaju mehaničke i matematičke funkcije koje određuju i širinu, odnosno sve tri dimenzije prostora. Data je i konstrukcija za prostor iza vetrobranskog stakla, položaj volana, prostor i položaj nožnih komandi, kao i ukupnog prostora za vozača. Dokazano je da na visinu od poda do krova vozila najveći uticaj imaju antropomere visine sedenja i potkolenice, dok na širinu antropomere potkolenice i natkolenice, a tek onda širina ramena, tako je unutrašnji prostor za vozače putničkog vozila određen visinom 1.250 mm i širinom za raširena kolena na nivo sedišta 926 mm.
