Comprehensive approach to topological and parametric optimization of ship structures

Object and purpose of research. The paper studies ship structures. The purpose of this work is to develop recommendations for algorithmization and use of ANSYS tools for topological and parametric optimization of ship structures. Materials and methods. Modern methods of topological and parametric optimization of structures were used. Main results. An algorithm for optimal design of ship structures has been developed. Based on the comprehensive use of topological and parametric optimization methods and modern software products, its practical application is illustrated by examples of optimal grillage design as part of the hatch cover in dry cargo vessel and the joint of aluminum panels as part of the hull of high-speed vessel. Conclusion. The developed algorithm was designed to find optimal design solutions in designing marine equipment. It allows to significantly reduce the weight of the designed structure and increase its resource compared to the closest analogues. The algorithm is a generalization of the experience of topological optimization, which finds the most rational structural and power scheme under the action of specified loads. The use of shape optimization at the final stage of the developed algorithm leads to an increase in the resource of the designed structure.
