Abstract

Abstract The inelastic deformation of a 30 m high-speed craft (HSC) subjected to slamming pressure is the main topic of this research. In this work, the commercial software package ABAQUS FEA is used to predict the structural behavior, especially in the hull area under the chine. Dynamic explicit solver simulations are done to predict plastic deformation. Before the principal analysis of the actual size of the ship hull structure model, the numerical studies were validated against relevant experimental data from the previous open literature. A reassessment of the design guidelines was also done to forecast the slamming load on the HSC structure. Then, with the slamming load pressure increased to the design limit, a parametric analysis was also conducted with two different idealizations of the pressure type: rectangular and triangular. Finally, this study identifies the variables that must be considered when calculating the degree of structural deformation brought on by slamming loads.

高速船底板在砰击载荷作用下的动力响应

摘要30的非弹性变形 m高速船（HSC）承受砰击压力是本研究的主要课题。在这项工作中，商业软件包ABAQUS有限元分析用于预测结构行为，特别是在机器下的船体区域。动态显式求解器模拟用于预测塑性变形。在对船体结构模型的实际尺寸进行主要分析之前，根据先前公开文献中的相关实验数据对数值研究进行了验证。还对设计指南进行了重新评估，以预测HSC结构上的砰击载荷。然后，随着砰击载荷压力增加到设计极限，还对压力类型的两种不同理想化进行了参数分析：矩形和三角形。最后，本研究确定了在计算砰击载荷引起的结构变形程度时必须考虑的变量。

期刊介绍： The aim of Curved and Layered Structures is to become a premier source of knowledge and a worldwide-recognized platform of research and knowledge exchange for scientists of different disciplinary origins and backgrounds (e.g., civil, mechanical, marine, aerospace engineers and architects). The journal publishes research papers from a broad range of topics and approaches including structural mechanics, computational mechanics, engineering structures, architectural design, wind engineering, aerospace engineering, naval engineering, structural stability, structural dynamics, structural stability/reliability, experimental modeling and smart structures. Therefore, the Journal accepts both theoretical and applied contributions in all subfields of structural mechanics as long as they contribute in a broad sense to the core theme.
