摘 要 船舶作为一种既能在水中航行又能停泊在港口进行运输或作业的重要交通工具, 它的载货量很大、运费较铁路航空很低、运营时间很长,因此受到越来越多人的关注 和青睐。船舶为了能装卸货物、避免恶劣天气、等泊位、检疫和候潮等常须抛锚停泊, 因此,锚泊系统的设计就显得尤为重要。为满足锚泊的需求性和安全性,本论文主要 开展以下一些工作:95146
1、搜集国内外有关锚泊系统的文献、资料,了解国内外锚泊系统发展的现状和趋 势,根据自己的研究想法并结合指导老师的建议确定最终研究方案;
2、确定临时锚泊地点周围海洋环境载荷并采用 AQWA 软件建立船舶锚泊的有限 元模型;
3、分别模拟一年一遇、五年一遇和十年一遇的典型工况下的船舶锚泊数值系统, 并校核船舶锚泊缆绳的张力,分析其运动响应特性。
4、得到数值计算结果,分析一系列相应的表格图像,判断锚链的选取是否符合各 大规范中所规定的安全使用要求。

Abstract The vessel is a significant means of transport that can be navigated in the water and can be parked in the harbor for transportation or operation。 It is very stockpile and has a very low freight cost and has a long operating time。 The concern and favor。 The design of the mooring system is particularly important in order to be able to load and unload cargo, to avoid bad weather, berths, quarantine and waiting tide。 In order to meet the demand and safety of mooring, this paper mainly carries out the following work:
1, to collect the literature and information on the mooring system at home and abroad, to understand the current situation and trend of the development of the mooring system both at home and abroad, to determine the final research plan according to their own research ideas and the suggestions of the instructors;
2, The finite element model of ship anchorage is established by using AQWA software to
determine the environmental load of temporary mooring site。
3, respectively, simulate the case of a year, five years and a decade under typical conditions of the ship anchoring numerical system, and check the ship anchor cable tension, analysis of its motion response characteristics。
4, get the numerical results, analyze the corresponding table image, determine whether the selection of the use of the safety requirements of the chain。
