Abstract

Marine engineering is very important as it is directly related to human life. 70% of our Earth is seas and rivers and most of the times the driving forces are provided by the flow of water which both provides buoyancy (to support the weight) and pushing forces due to flow. Balancing of the component is of main concern over the water surface and if it is controlled it is safer than travelling in airplanes where main objective is higher speeds than carrying higher loads. That’s why I chose this topic as my topic of research. In the present work, the hydro-elastic analysis of a marine component (ship’s hull) has been performed in order to facilitate the design of hull because its design plays key role for the safe voyage of a ship. The uniqueness of this design is that is does not involve complex geometries. First of all, a hull has been created using AutoCAD and Solid Edge. It was then analyzed assuming different loading condition like pressure and bending effects due to the ocean waves. Various possible movements i.e. rolling, yawing, pitching, heaving, slamming etc. of the hull in the marine environment have been mathematically formulated and then a detailed finite element analysis of resulting pressures and inertia forces due to the motion has been made. As a result of analysis, the safe bending, shearing and normal stresses and strains were automatically calculated by using Auto-FEM. The importance of this work is that the method of analysis can be applied and extended to other marine components undergoing the same type of loading conditions.
