20.500.12556/RUL-102621 Kontrola statične in trdnostne varnosti nosilne konstrukcije krožne žage Control of static safety and strength of a circular saw's carrying construction Potrebe po modernizaciji proizvodnje podjetja silijo v predelavo ali nakup novih strojev. V okviru diplomske naloge je prikazan primer predelave nosilne konstrukcije krožne žage iz podjetja, ki se ukvarja s proizvodnjo poliuretanske pene. Na obravnavani žagi je bil za modernizacijo in za večjo efektivnost linije odstranjen eden izmed nosilcev nosilne konstrukcije žage. Posledično se je pojavil problem varnosti obratovanja žage po predelavi. V prvem delu diplomske naloge je predstavljena energijska metoda na osnovi principa virtualnega dela. V drugem delu je predstavljen konkreten primer nosilne konstrukcije krožne žage in izračun le-te. V zaključku diplomskega dela je prikazan še izračun napetosti v kritičnih nosilcih in palicah. Nowadays the society and the industry are facing constant changes and developments. Consequently, companies are often forced to reconstruct machines or purchase new machinery to modernize their production. This thesis aims at presenting a reconstruction of a frame structure of a circular saw used in a company that manufactures polyurethane foam. When trying to modernize the circular saw and make the production more effective, a structural element of the circular saw’s carrying construction has been removed. As a result, the issues related to the safety of reconstructed saw are to be addressed. The first part of the thesis focuses on energy methods and principle of virtual work. What follows is a detailed representation of the addressed frame structure of a circular saw and its analysis. The calculations of capacities and stress related to circular saw’s structural elements are presented as well. nosilna konstrukcija energijske metode mešani sistem princip virtualnega dela statično-trdnostni izračun statično nedoločen sistem carrying structure of a circular saw energy methods frame structure principle of virtual work static and strength calculation statically indeterminate system true false false [M.
