船体板和加筋板的屈曲及极限强度研究综述

Research development of buckling and ultimate strength of hull plate and stiffened panel

  • 摘要: 船体板和加筋板的屈曲及极限强度是船舶结构强度设计的重要内容,近年来研究成果颇丰,为了能够更方便地对其展开学习和研究,对近十几年来国内外钢质船体板和加筋板的屈曲及极限强度研究进展进行综述。主要叙述了静态加载范畴下的研究现状,分别按照试验法、数值计算法、解析法和综合性方法4种不同研究方法,对完整结构和含有开口、裂纹、腐蚀、凹痕几种不同损伤的非完整结构,在承受单一载荷或联合载荷作用下的极限强度研究成果进行系统的概述,并介绍加筋板低周疲劳和动力屈曲的研究必要性和部分研究成果,讨论各研究方法的优劣性,对一些重要的定性研究结论进行汇总,指出6个需要进一步展开研究的问题。

     

    Abstract: Buckling and ultimate strength of hull plate and stiffened panel are important contents in the de-sign of ship structures, have achieved plenteous results in recent years. The research development of buck-ling and ultimate strength of steel hull plate and stiffened panel in the past decade at home and abroad is re-viewed for the convenience of carrying out studies and researches. The case of static loading is emphatical-ly described, the cyclic loading and dynamic loading are also introduced. A systematical overview is pre-sented for intact structures and damaged structures under single load or combined loads, in accordance with four kinds of research methods, which are experiment, numerical computation method, analytical method and comprehensive approach. The superiority and inferiority of each research method are assessed. Significant achievements are summarized, and six further problems are identified for the future study.
