Abstract

U gotovo svakom proizvodnom pogonu, hali ili skladištu nalazi se neki tip dizalice ili transportnog uređaja. U manjim proizvodnim pogonima najčešće su konzolne dizalice s horizontalnim dohvatnikom. Ovisno o težini podizanja, postoje različite izvedbe nosive konstrukcije koje oblikom podsjećaju na konzolu. Ovisno o konstrukcijskim zahtjevima pristupa se proračunu dizalice. Većina dijelova dizalice su standardni i propisani normom. Analitički izrazi za provjeru naprezanja pojedinih dijelova su približni, ali ta nesavršenost analitičkih izraza uzeta je u obzir kod definiranja vrijednosti dopuštenih naprezanja. Ovaj rad bavi se numeričkom analizom konzolne dizalice s horizontalnim dohvatnikom. Provedena je 2D analiza nosive konstrukcije dizalice, 3D analiza određenih sklopova iz nosive konstrukcije, analiza sklopa kuke i analiza sklopa skretne užnice. Analize su provedene u komercijalnom programskom paketu Abaqus®. Rezultati dobiveni numeričkom analizom su uspoređeni s analitičkim rezultatima ili dopuštenim naprezanjima propisanima normom, te je na temelju toga izveden zaključak.

Abstract (english)

Every production facility or stockroom have some kind of lifting equipment or crane. In small production facilities the most common is fixed crane with horizontal jib. Calculation of crane depends on requirements of construction. The most parts of crane are designed by standard. Standard calculations for stress checking of parts are approximate, and that deficiency is probably taken into with defining permissible stress. The main idea of this work is numerical analysis of fixed horizontal jib crane. 2D analysis was preformed for main construction of crane, 3D analysis was preformed for ceratin assemblies of main constrution, analysis of hook assembly and analysis of swivel pulley assembly. Numerical analysis was preformed in the comercial software package Abaqus®. The resultats of numerical analysis are compared with results obtained analytically or with permissible stress by standard, and finally comes conslusion.
