Abstract
Tema ovog rada je projektiranje konstrukcije glavnog rebra broda za prijevoz automobila i kamiona (PCTC-pure car truck carrier). Dimenzioniranje elemenata konstrukcije provedeno je po pravilima klasifikacijskog društva Det Norske Veritas. Posebna pažnja posvećena je dimenzioniranju paluba opterećenih kotačima vozila. Za njih je provedena analiza senzitivnosti mase uzdužnih elemenata konstrukcije u ovisnosti o razmaku poprečnih okvira i uzdužnjaka. Ispitane su tri projektne varijante razmaka okvira i uzdužnjaka s ciljem dobivanja optimalne varijante po kriteriju najmanje mase. Potom je istražen utjecaj broja upora na visinu palubnih sponja te njihov utjecaj na visinu broda. Za projektnu varijantu najmanje mase izrađen je 3D MKE parcijalni model u programu MAESTRO kako bi se provela analiza metodom konačnih elemenata. Analiza je napravljena za četiri različita slučaja opterećenja prema uputama DNV-a, te su nepodobni elementi strukture redimenzionirani tako da zadovolje sve kriterije podobnosti. Naposljetku, napravljena je usporedba masa između modela prije i nakon redimenzioniranja konstrukcije pri čemu su zadovoljeni svi kriteriji strukturne podobnosti.
Abstract (english)
The objective of this study is structural design of midship section of a ship for transportation of cars and trucks (PCTC-pure car truck carrier). Defining of the construction elements was done in accordance with the rules of Det Norske Veritas (DNV) classification society. Particular attention was given to the defining of decks under wheel load. For them, a sensitivity analysis of mass of longitudinal construction elements in dependence of the web frame spacing and longitudinals spacing was performed. Three variants of the web frame spacing and longitudinals spacing were studied in order to obtain an optimal variant by the criterion of minimal mass. Then, the influence of the number of pillars on the height of transverse beams and their influence on the ship height was investigated. For the project variant of a minimal mass, 3D FEM partial model was created in software MAESTRO in order to conduct a finite element method analysis. The analysis was made for four different load cases in accordance with the rules of DNV and inadequate structural elements were redefined in order to meet all the structural adequacy criteria. Finally, the comparison of a structural mass was made between the prototype model and the final model after redefining the structure to satisfy all structural safety criteria.
