Abstract

In this paper, Finite Element Analysis was used to simulate ship hatch covers with different grid geometries viz. Square grid, Inclined grid, Diamond grid and Honeycomb grid. The entire finite element analysis results were generated by ANSYS® 2022 workbench environment. The hatch cover provides an air tight barrier protection for the cargo. For the present simulation the original hatch cover dimensions are used (21000 × 14000 × 300 mm). The principle objective of the present paper is aimed at proposing a light-weight material, so called glass fibre reinforced plastic material over the existing steel to reduce the weight for the cargo ship to improve the efficiency by reducing fuel consumption so that dead weight is downgraded. Glass fibre reinforced hatch cover also reduces man power for the process of handling the hatch cover. Based upon the finite element analysis outcomes of different grid geometries are Square, Inclined, Diamond, Honeycomb optimal core grid of hatch cover was chosen. A scaled down model of hatch cover using glass fibre reinforced plastic with an optimal grid structure has been also developed in this paper.

船用舱口盖使用轻质玻璃钢复合材料:实验和有限元模拟

本文采用有限元分析方法对不同网格几何形状的船舶舱口盖进行了数值模拟，分别为方形网格、倾斜网格、菱形网格和蜂窝网格。整个有限元分析结果在ANSYS®2022工作台中生成。舱口盖为货物提供气密屏障保护。在目前的模拟中，使用了原始舱口盖尺寸(21000 × 14000 × 300毫米)。本论文的主要目标是提出一种轻量化材料，即所谓的玻璃纤维增强塑料材料，在现有的钢铁上减轻货船的重量，通过减少燃料消耗来提高效率，从而降低自重。玻璃纤维增强舱口盖也减少了处理舱口盖过程的人力。根据不同网格几何形状的有限元分析结果，选择了方形、倾斜、菱形、蜂窝状的最优舱盖核心网格。本文还建立了具有最优网格结构的玻璃钢舱盖缩尺模型。

期刊介绍： Engineering Solid Mechanics (ESM) is an online international journal for publishing high quality peer reviewed papers in the field of theoretical and applied solid mechanics. The primary focus is to exchange ideas about investigating behavior and properties of engineering materials (such as metals, composites, ceramics, polymers, FGMs, rocks and concretes, asphalt mixtures, bio and nano materials) and their mechanical characterization (including strength and deformation behavior, fatigue and fracture, stress measurements, etc.) through experimental, theoretical and numerical research studies. Researchers and practitioners (from deferent areas such as mechanical and manufacturing, aerospace, railway, bio-mechanics, civil and mining, materials and metallurgy, oil, gas and petroleum industries, pipeline, marine and offshore sectors) are encouraged to submit their original, unpublished contributions.
