Modeliranje mehanskega odziva lupinske konstrukcije inovativne zemeljske postaje : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoTomec, JanNapihljive konstrukcije v praksi niso zelo pogoste, saj so zahtevne z vidika dimenzioniranja zadostne togosti in vzdržljivosti. V primeru dobrega načrtovanja pa ima lahko taka konstrukcija številne ... prednosti. Ponavadi so lažje in cenejše, v konkretni aplikaciji za zemeljske postaje pa je pomembno tudi, da s kovinskimi elementi ne motijo elektromagnetnih signalov. Ker so te postaje postavljene v okolje, so izpostavljene vsem vrstam vremenskih vplivov. V tej nalogi je predstavljena teorija, ki je potrebna za mehansko analizo napihljive lupinske konstrukcije, prikazani so analitični in eksperimentalni validacijski primeri, na koncu pa je dodan še numerični model zemeljske postaje Stream. Specifika sferične geometrije je povzročila zanimive deformacijske oblike pri tlačnem obremenjevanju. Taki konstrukciji pri preseženi kritični obremenitvi močno pade togost, zaradi česar je prikazan tudi postopek določevanja kritične obremenitve.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
