Optimization of Lightweight Structure for Ship Railings Based on Abaqus

Abstract

With the development of the shipbuilding industry, the requirements for the safety and corrosion resistance of ship structural components are becoming increasingly high. Most of the components used in traditional ships are made of steel, which cannot meet the requirements of corrosion resistance and safety for existing ships. In order to improve the structural safety and corrosion resistance of ship railings, as well as their requirements for lightweighting, this article proposes a lightweight design for ship railing structures based on the existing T700 carbon fiber composite material railing structure. Carbon fiber composite materials have the advantages of light weight, high strength, and high modulus. Based on the anisotropy of carbon fiber composite fibers, the characteristics of overlapping/weaving structures, and the influence of the interface between carbon fiber composite materials and metal materials on the strength of ship railing structures, a finite element simulation model of carbon fiber composite materials is established. By setting constraints such as volume fraction, stress, strain, displacement, etc. based on the simulation model, the layout of materials in the optimization results is used to guide the design of the structure. The size parameters of the ship railing barrel are optimized, and the topology structure is optimized. Thus achieving lightweight design of ship railings and meeting the requirements for lightweight, safety, service life, and corrosion resistance of ship structural components.
