Abstract

Razvojem industrije jaružanja, paralelno su se razvijali složeni i sofisticirani brodovi za obavljanje te djelatnosti – jaružala. Za razliku od klasičnih trgovačkih brodova, jaružala zbog svog kompleksnog načina rada i potrebe za složenim proračunima tijekom projektiranja, spadaju u grupu specijalnih plovila. Jedan od kritičnih detalja jaružala opremljenog sjekačem (e. cutter suction dredger) sa stanovišta čvrstoće, su kolica pilona koja će se obraditi u okviru ovog diplomskog rada. U uvodnom dijelu rada dan je kratki opis jaružanja kao djelatnosti, te različitih vrsta jaružala sa naglaskom na usisna jaružala, odnosno usisna jaružala opremljena sjekačem. U nastavku je analiziran princip rada kolica pilona, te su definirani kritični slučajevi opterećenja i razrađene funkcionalne sheme prijenosa sila i momenata za spomenute slučajeve. Te će sheme poslužiti kao osnova u daljnjoj analizi, odnosno za definiranje kritičnih slučajeva opterećenja u konceptualnoj fazi projekta kada nije moguće napraviti MKE model cijele konstrukcije. Slijedi izrada parcijalnih MKE modela za odabrane dijelove konstrukcije i analiza u programskom paketu FEMAP/NASTRAN.

Abstract (english)

With development of the dredging industry, complex and sophisticated ships were also developed to perform dredging activities. Unlike traditional merchant ships, dredgers belong to the group of special vessels, due to theirs working modes and need for complex calculations during design. One of the critical details featured in cutter suction dredgers, from the standpoint of the strenght, is spud carrier, which will be analysed within this thesis. In the introduction, description of the dredging activities, as well as description of different types of dredgers are given. Emphasis is on suction dredgers, more specifically, cutter suction dredgers. After that, working principle of spud carrier is analyzed and critical load cases are defined with related layouts of forces and moments. These layouts will serve as a basis for further analysis and for defining critical load cases in the conceptual phase of the project, when it is not possible to make a FEM model of the entire structure. In the end, partial FEM models are made for selected parts of the structure and analyzed with FEMAP/NASTRAN software.
