Sažetak
Uljanik shipyard has contracted University of Zagreb (UZ), Faculty of Mech. Eng. and Naval Arch. to perform 3D FEM analysis of Yard 437-439 using MAESTRO software available at University of Zagreb. The coarse-mesh, full-asymmetric, global car carrier FE model was developed (Pt B,Ch 7, App 2). It simultaneously provides boundary conditions for fine mesh analysis of the crack areas on all three watertight bulkheads (Fr 51/99/147) caused by the transverse racking induced forces . Full ship 3D FEM model has 47 064 DOF and 18 462 macroelements (10164 stiffened panels and 8298 beams). Loading condition 3 (Cars on decks 1 to 11, 100% fuel and stores) was adjusted to R.I.N.A requirements for racking (Pt B, Ch 5, Sections 3-5). Pressures were calculated by R.I.N.A Rules.All masses (light ship, cars, etc.) were given corresponding accelerations based on the acceleration vector components calculated from the Rules (Pt B, Ch 5, Section 3), . Car masses were concentrated in mesh nodes of the corresponding decks.Fine mesh models for Detail Stress Analysis (DSA) using "top down approach" were developed. Boundary conditions to DSA models were automatically transferred from MAESTRO global model.Stress levels were adjusted to R.I.N.A Rules (Pt B, Ch 7, Section 4). Ship satisfies R.I.N.A racking requirements. Brackets on Fr 99. were highly stressed ( s vonMises, max = 239 N/mm2) and adequate material quality should be assured. The bracket's free end preparation should be performed to avoid crack initiation.
