Sažetak
The coarse-mesh, full-asymmetric, global car carrier FE model has been developed. It simultaneously provides boundary conditions for fine mesh analysis of the critical areas on all three watertight bulkheads 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). Load case from longitudinal strength calculation (Cars & trucks, 100% fuel and stores) has been adjusted to requirement for the maximal metacentric height according to Classification Societies requirements. MESTRO Balancing routine is used to zero the reactions in support nodes. Pressures are calculated by Classification Societies Rules (Det Norske Veritas and Registro Italiano Navale). All masses (light ship, cars, etc.) have been subjected to corresponding accelerations based on the acceleration vector components calculated from the Rules. Car masses are concentrated in mesh nodes of the corresponding decks. Fine mesh models for Detail Stress Analysis (DSA) using "top down approach" have been developed. Boundary conditions to DSA models have been automatically transferred from MAESTRO global model. Critical areas are clearly identified in global and DSA models. Structural modifications (brackets, inserted plates and pillar structure) have been designed and cross checked.
