Optimizacija mehanizma upogibanja pločevine : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoArzenšek, AnžeDelo obravnava dimenzijsko sintezo gibanja sedemzgibnega mehanizma na podlagi genetskega algoritma. Sedemzgibni mehanizem je del stroja za upogibanje pločevine, ki določa trajektorijo gibanja ... upogibne letve in obremenitveno prenosno funkcijo. Z gibanjem letve deformiramo oziroma upogibamo pločevino, njen tir gibanja pa vpliva na kakovost končnega izdelka (deformirano pločevino) in velikost obremenitev v mehanizmu. V nalogi je opisan postopek izdelave optimizacijskega algoritma, ki na podlagi izračuna kinematičnih točk mehanizma, približa gibanje upogibne letve referenčnemu tiru. Referenčni tir opiše idealni tir gibanja upogibne letve, katerega oblika in velikost je odvisna od geometrije stroja in debeline pločevine, njegovi dve glavni prednosti pa sta: gibanje letve brez poškodovanja pločevine in zmanjšanje skupne sile z ničnim relativnim gibanjem letve glede na deformacijo pločevine. Razvit je optimizacijski 2D model sedemzgibnega mehanizma gibanja letve, ki na osnovi velikosti oblikovnih spremenljivk poda dejanski tir mehanizma, namenska funkcija pa izračuna odstopanje tira gibanja letve od referenčnega tira. Na podlagi različnih velikost mehanizma in njihovih vrednostih namenskih funkcij, genetski algoritem poišče najprimernejšo rešitev, katere tir gibanja je najprimernejši. Razvit algoritem je sestavljen tako, da s spreminjanjem konstantnih oblikovnih spremenljivk spreminjamo velikost in obliko optimiziranega mehanizma, tir gibanja pa se ohrani. Tako dobimo več različnih oblik mehanizma s podobnim tirom in povečamo možnost izbere najprimernejšega.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
