Use of Hydroelasticity Analysis in Design

摘要

The application of hydroelasticity analysis in various stages of the design process can provide improved predictions of global wave-induced loads, such as torsional moments for mono-hulled vessels and splitting moments for multi-hulled vessels, by modelling the physical problem more accurately. The complexities involved in generating the data for fluid-flexible structure interaction (FFSI), on the other hand, can be considered as a disincentive to its extensive use by designers. This particular issue led to the work described in this paper on the application of 3D hydroelasticity as an analysis tool for the dynamic behaviour of ships in waves through the use of the G-Hydroflex portal. This web-enabled application allows users to solve FFSI problems by utilising large Grid-based computer resources. The portal also allows geographically dispersed designers to work together with ease and security. Following the description of the portal architecture, applications to a range of mono- and multi-hulled vessels are illustrated and future improvements discussed.
