Abstract

U ovom radu je projektirano glavno rebro broda za prijevoz tekućeg tereta u unutarnjoj plovidbi. Analiziran je referentni model dimenzioniran prema pravilima Hrvatskog registra brodova te druge varijante koje su proizašle iz tog modela. Variranjem razmaka uzdužnjaka i okvira analiziran je utjecaj na pojedine konstrukcijske elemente. Naglasak u samoj analizi je na procjeni mase.
Nakon modeliranja i analiziranja referentnog modela napravljeno je redimenzioniranje konstrukcijskih elemenata programom Mars Inland u kojemu su implementirana pravila “Rules for the Classification of Inland Navigation Vessels“. Nakon redimenzioniranja predložene su dodatne varijante s različitim razmacima uzdužnjaka i okvira kako bi se za konceptualnu fazu konstruiranja broda pronašla pogodna varijanta koja bi poslužila kao polazna točka za razvoj broda. Dimenzije okvira i rebrenica su preuzete iz tehničkih nacrta za referentni model Hrvatskog registra brodova.
S obzirom na procjenu mase, među predloženim varijantama odabrana je varijanta koja teži najmanjoj masi i uspoređena je s referentnim modelom. Nakon analize je razmotren zahtjev uzdužne čvrstoće na primjeru glavnog rebra odabranog modela.

Abstract (english)

In this paper has been made structural design of ship midsection of inland tanker. Reference model designed by the rules of Croatian Register of Shipping and the other suggested models have been analised. By varying the spacing of longitudinals and web frames it has been analyzed how they affect on certain groups of construction elements. The emphasis was on assessment of construction mass.
Redimensionating of construction elements has been made after modeling and analysing reference model. Redimensionating has been carried out with the help of Mars Inland program which has Bureau Veritas “Rules for the Classification of Inland Navigation Vessels“ implemented in itself. After redimensionating, other variations have been given with changed spacing of frames and longitudinals so the favorable variant could serve as starting point for conceptual phase of ship development. Dimensions of web frame and floor have been taken from reference model made by Croatian Register of Shipping.
With respect to carried out analysis of construction mass, favorable variation has been selected and compared to reference model. After analysis, ultimate longitudinal strength of ship hull criteria has been observed on the example of main frame of selected favorable variant.
