The purpose of the project is to create a procedure for the structural optimization of a cruise ship section. The overall goal is to find a design of the ship section with minimal weight while respecting the design constraints in terms of maximal allowable stresses, deflections and vibrations. The work will involve: 1) Development of an APDL parametric model of a cruise ship section; 2) Connection of the developed APDL parametric model with a PSO algorithm for the purpose of finding an optimal design. APDL (Ansys Parametric Design Language) is a programming language of a commercial FE software ANSYS which is used to build parametric FE models. PSO (Particle Swarm Optimization) is an optimization procedure used in connection with APDL script to find an optimal design. Both APDL model and PSO algorithm will be based on the existing ones and the student will need to adjust them to the requirements of the current project. The student will be guided by the institute’s team of structural optimization experts in cooperation with an industry partner.
