Abstract
S razvojem računalne tehnologije i automatizacije, sve je više autonomnih brodova na moru. Zbog svojih specifičnosti uslijed nedostatka posade, ti brodovi mogu biti u opasnosti od izazivanja sudara. Iako nije moguće zaštititi ih od svih vrsta sudara, potrebno je promotriti najizglednije sudare, a to su frontalni pri manjim brzinama. Model broda izrađen je u CATIA V5 programskom paketu po nacrtima brodice za traganje i spašavanje. Za zaštitu odabran je integrirani bokoštitnik od polietilenske pjene. Mreža konačnih elemenata izrađena je FEMAP/NX Nastran programskom paketu. Promatrana su dva tipa sudara: frontalni okomiti i frontalni pod kutem od 30 stupnjeva. Za oba slučaja nelinearnom analizom metodom konačnih elemenata u programskom paketu LS Dyna ispitana je maksimalna brzina brzina sudara koju brodska konstrukcija može pretrpjeti bez trajnih oštećenja. Također je ispitana analiza sudara maksimalnom brzinom i sudara nezaštićenog broda. Za sve analize dan je slikovni prikaz naprezanja i deformacija i dijagrami pada kinetičke energije.
Abstract (english)
With the development of computer technology and automation, there is an increasing number of autonomous ships in operation. Due to the lack of human involvement, these ships may be at risk of causing collisions. Although it is not possible to protect the ship from all types of collisions, there are several most likely collision situations in which the ship could be found and those include frontal collisions at lower speeds. The ship model was created in the CATIA V5 software package based on search and rescue boat design. An integrated polyethylene foam fender was selected for protection. Finite element mesh was generated in FEMAP/NX Nastran software package. Two types of collisions were observed: vertical head-on and head-on at a 30-degree angle. For both cases, a nonlinear finite element analysis was conducted using the LS Dyna software package to determine the maximum collision speed that the ship structure can withstand without permanent damage. An analysis of a collision at maximum speed and a collision of an unprotected ship was also conducted. For all analyses, a graphical representation of stress and deformation along with kinetic energy decline diagrams were provided. Key words: Ship collision, boat fender, nonlinear FEM analysis
