摘要

摘要:冰载荷是影响极地船舶航行安全的重要环境因素,而对船舶结构的现场监测是获取冰载荷的可靠途径.鉴于船-冰相互作用的复杂性, 目前还难以直接测量冰载荷,一般通过结构应变、六自由度运动参数等船舶结构局部或总体响应的测量数据间接反演冰载荷.根据冰载荷的作用范围,本文将船舶结构冰载荷现场监测划分为局部冰载荷现场监测与总体冰载荷现场监测两大类.对国内外18艘极地船舶冰载荷现场测量试验的开展时间、试验海域、测量方案等信息进行了系统的总结和分析.从基本原理、适用范围、应用现状和发展前景等方面全面地介绍了船舶结构冰载荷反演的影响系数矩阵法、支持向量机法、格林函数法、运动参数法和功能关系法,并重点分析了"MV Timofey Guzhenko"极地穿梭油轮与"IBRV Araon"破冰考察船的冰载荷测量结果.在此基础上对船体局部冰压、冰力峰值、冰载荷概率分布和冰激振动加速度等相关研究进展进行了深入的讨论.最后从测量技术、反演方法、冰载荷特性等方面剖析了当前船舶结构冰载荷现场监测中存在的问题,并探讨了相应的研究方向.本文对国内外极地船舶冰载荷现场测量与反演方法的论述可为后续研究与工程应用提供科学参考,从而更好地促进我国极地船舶的抗冰结构设计与冰区航行技术的发展.

Abstract:The ice load is an important environmental factor affecting the navigation safety of polar ships. The field monitoring of ship structure is a reliable approach to obtain the ice load. In view of the complexity of the ship-ice interaction, it is currently difficult to measure the ice load directly. Generally, the ice load is inverted indirectly through the measured data of the local or global response of ship structure, such as structural strains and six-degrees-of-freedom motion parameters. Firstly, according to the action scope of the ice load, the monitoring methods of the ice load on ship structure are divided into two categories in this paper, i.e., those for local ice loads and those for global ice loads. The information such as the date, the area, and the measurement scheme of ice load field measurements for 18 polar ships is systematically summarized and analyzed. Then, five ice load inversion methods for ship structure such as Influence Coefficient Matrix Method, Support Vector Machine Method, Green's Function Method, Motion Parameter Method, and Work-energy Relationship Methodare comprehensively introduced from the aspects of fundamental principles, application scope, strengths and weaknesses, application status, and development prospects. The field measurement results of the Arctic shuttle tanker, MV Timofey Guzhenko, and the icebreaking research vessel, IBRV Araon, are emphatically analyzed. On this basis, the related research progress of the local ice pressure, the peak ice force, the probability distribution of ice loads, and the ice-induced vibration acceleration are discussed in depth. Finally, the problems existing in the ice load field monitoring for ship structure are dissected from three aspects, including measurement technology, inversion methods, and ice load characteristics. Moreover, the corresponding research directions are discussed. The review of field measurements and inversion methods of ice loads on ship structure in this paper can provide scientific reference for subsequent research and engineering applications, so as to better promote the development of ice-resistant structure design and ice navigation technology of polar ships in our country.
