TOPOLOGY OPTIMISATION METHOD APPLIED TO FABRICATION OF DEVELOPABLE SHIP HULLS
During the fabrication process of small-size ship hulls made of fiber reinforced plastic (FRP), to reduce the error of the assembly from the real geometry, appropriate loads are applied to some locations of the assembly. There are many ways to apply the loads to obtain a desired deformed shape. This article describes the use of the topology optimization tool to find an optimal load distribution that has a minimal loading area and magnitude, yielding the desired deformed shape. The authors report on a continuum-based design sensitivity analysis (DSA) method for non-shape problems that they developed for linearly elastic structural systems. The first-order variations of energy form, load form, and structural responses with respect to the non-shape design variables are derived. The Mindlin plate element is selected to discretize the structural domain. The authors integrate three methods into one unified and automated framework for numerical implementation: the finite element analysis method, the developed DSA method, and a gradient-based optimization method. They conclude that the numerical results of plate forming and hull forming problems show very good agreement with intuitive designs.
