Abstract

Sve veći zahtjevi postavljaju se pred inženjere brodogradnje s obzirom na udobnost putnika i posade, odnosno njihanja broda na valovitom moru, prema tome pomorstvenost postaje važan kriterij pri određivanju forme broda. Osobito je važno u ranim fazama projektiranja moći odrediti karakteristike forme zbog čega se u praksi nalazi sve veća primjena i razvoj računalnih alata za procjenu hidrodinamičkih karakteristika forme.
U ovome radu razvijen je programski modul Hydrostar unutar programa otvorenog koda d3v-gsd koji omogućuje korisniku automatiziranu pripremu ulaznih podataka za program HydroSTAR (Bureau Veritas) za analitički zadanu parametarsku formu, te provedbu proračuna pomorstvenosti. Rad programskog modula Hydrostar prikazan je i opisan dijagramima toka. Zadanu analitičku formu moguće je modificirati varijacijom 11 različitih parametara (Lpp, Bm, D, MSfull, AFTfull, FWDfull, TRfull, TB, TD, FWK, ACU). Na temelju razvijenog alata provedena je analiza utjecaja parametara na odzive ljuljanja i posrtanja, čiji su rezultati prikazani.

Abstract (english)

Naval architects are confronted with more demanding requirements for crew and passenger comfort, respectively ship motions in sea environment, so seakeeping performance is becoming important criteria in the process of hull form design. It is especially important to estimate hull form characteristics in the early stages of the design process, which is the reason of more frequent use and development of the computer tools for estimating hydrodynamic characteristics of hull form in the naval architecture practice.
This paper represents the description of the program module Hydrostar, that is developed in the open source program d3v-gsd, which enables automatic generation of input files for seakeeping software HydroSTAR (Burea Veritas) and seakeeping calculation for the analytic parametric hull form. The analytic hull form can be modified by variation of 11 different parameters (Lpp, Bm, D, MSfull, AFTfull, FWDfull, TRfull, TB, TD, FWK, ACU). Effect of hull form parameters on roll and pitch motions analysis is conducted with developed tool and results are shown, respectively.
