Abstract

Cilj zadatka je konstruirati brodsku pasarelu promjenjive dužine koja će omogućiti siguran transport putnika i robe između plovila i kopna. Uključeni su dodatni uvjeti i ograničenja, pri čemu je naglasak na tome da konstrukcijsko rješenje bude prilagođeno za vanjsku izvedbu, odnosno za ugradnju na krmi plovila. U prvom dijelu rada prikazano je upoznavanje sa sustavom transporta putnika i robe u svim vrstama prometa, s naglaskom na pomorski promet. Početna faza razvoja podrazumijeva definiranje problema i apstraktnih ciljeva koje proizvod mora zadovoljiti. U ovoj fazi prikazana je analiza postojećih proizvoda, kao i njihove karakteristike. Nadalje, korištenjem baze patenata izvršen je i pregled postojećih patenata. Sljedeća faza razvoja odnosi se na definiranje funkcija te izradu funkcijske dekompozicije proizvoda koja je poslužila kao baza za izradu morfološke matrice. Morfološka matrica sadrži moguća rješenja za funkcije koje uređaj mora zadovoljiti. Na temelju morfološke matrice izrađena su tri koncepta koja su ocijenjena prema kriterijima definiranim tijekom pretrage tržišta. Za najbolje ocijenjeni koncept provedena je daljnja razrada, uključujući proračun pogona, mehanizama i nosive konstrukcije. Naposlijetku, za proizvod su izrađeni CAD model i tehnička dokumentacija.

Abstract (english)

The aim of this thesis was to design a variable-length gangway which will ensure the safe transportation of passengers and goods between the dock and the boat. Additional restrictions were included and, outside conditions as well as mounting were considered. Firstly, general transport system informations were provided with an emphasise on maritime transportation. After defining the problem and abstract goals, market and patent searches were carried out. The next phase was related to defining the device and components, followed by functional modeling. Functional modeling served as a base for creating the morphological matrix, which contains possible solutions considering each function defined. Following that step, three concepts were created and evaluated by criteria defined during the market research. The highest rated concept was developed further, which included drive calculation, mechanism selection and supporting structure. Finally, 3D CAD model and technical documentation were created.
