Analiza utrujanja nosilnega okvirja delovnega stroja z napetostnim pristopom : diplomska naloga univerzitetnega študija

Novšak, Anže

V diplomskem delu obravnavamo dobo trajanja nosilnega okvirja delovnega stroja, za katerega imamo podane robne pogoje ter tipicen obremenitveni blok zgodovine obremenjevanja. Na osnovnem CAD modelu ... nosilnega okvirja dodamo zvare na predvidenih zvarnih mestih ter vijake ustreznih dimenzij za pripravljene izvrtine na prirobnici. Konstrukcijo pregledamo in dolocimo mesta najverjetnejših inicialnih poškodb. V raziskavi sledimo napetostnemu pristopu, po katerem ugotavljamo cas do odpovedi zaradi utrujanja na kriticnih kontrolnih mestih nosilnega okvirja. Za izvedbo Rainflow metode izlocanja ciklov iz obremenitvene zgodovine in nadaljnji preracun dobe preživetja kreiramo algoritem v programskem jeziku R. Rezultati dobe trajanja se v grobem opirajo na ovrednotenje jeklenih konstrukcij po standardih Evrokod 3-1-9 ter DIN15018. Izracuni kažejo, da konstrukcija zelo verjetno ne ustreza omenjenima standardoma.
