Abstract

U današnje je vrijeme bočno porinuće sve više prisutno u raznim brodogradilištima zbog niza
pogodnosti koje vuče sa sobom. U prvom dijelu ovog rada izvršena je statička analiza klizne staze
potrebne za bočno porinuće i dan je slikovni pregled mjesta pojave najvećih naprezanja i najvećih
deformacija koji su se pojavili tijekom procesa porinuća.
Drugi dio rada ispituje oblik produženih kliznih staza koji se koristi zbog nedovoljne dubine
morskog dna i rizika da bi konstrukcija koja se porinuje mogla udariti od dno. Kao i u prethodnom
dijelu, dan je slikovni pregled naprezanja i deformacija koji se pojavljuju uslijed statičkog
opterećenja.
Proračun obadviju konstrukcija je proveden metodom konačnih elemenata uporabom programskog
paketa Femap/NX Nastran

Abstract (english)

Nowadays, side ship launching is more and more present in various shipyards due to several
benefits that is brings with it. In the first parti of this paper a static analysis of the slideway required
for transversal ship launching was performed and an image overview of the location of the biggest
stresses and biggest deformation that occurred during the launching process was given.
The second part of the paper examines the shape of the extended slideway which is used due to the
insufficient depth of the seabed and the risk that the structure could hit the bottom. As in the
previous section, a image overview of the stresses and deformations that occur due to static loading
is given.
The calculation of both constructions was performed by the finite element method using the
Femap/NX Nastran software package
