The conditions of the lashing system on board chinese ro - ro ships are investigated and the western research results of the same problem are introduced and compared . in chapter 3 , mechanical and mathematical models for the estimation of the loads in the lashing systems of road vehicles on board ro - ro ships are developed . the result is calculated and simulated by the computer program which was provided by professor s . turnbull from oxford university , britain 通过比较国外同类问题的研究方法，针对我国现有滚装航线上实际运输生产中的车辆绑扎系固的状况，作者采用了建立滚装船上车辆绑扎系固力学和数学模型，并结合专门的计算机计算程序计算和模拟结果的方法，对滚装船上车辆绑扎系固的绑索的受力情况进行了全面的定量分析和计算。
The thesis , which is divided into six parts , reviews the history of the ro - ro ship and the stipulations of imo concerning the securing of cargo on ro - ro ships . the urgency for china to develop the technology standard for the vehicle securing on ro - ro ships is provided and reason is discussed 本文在介绍了滚装船舶及国内外滚装运输的基本情况和imo对滚装船舶安全性的规定的基础上，提出并讨论了从定量角度研究长期以来影响滚装运输的重要技术问题? ?滚装船上车辆绑扎系固问题? ?的必要性和迫切性。
Firstly , roll - on roll - off ships are introduced in detail . then this thesis analyzes the actuality of roll - on roll - off fleets in the world , and introduces international well - known shipping companies that engage in roll - on roll - off transportation of automobile , including their fleets , market share , operating status and development in the future 本文首先对汽车滚装船作了详细的介绍，而后对世界滚装运输船队的现状作了简要的分析，并对国际知名的几大汽车滚装运输船公司的运力、市场份额、经营现状以及未来发展方向作了具体的介绍。
The prime goal of this paper is to conduct the fatigue analysis for certain type of structural details of 12300t ro / ro vessel by means of three different approaches stated in dnv classification notes " the fatigue assessment for ship structures " and contrast the results from the three different methods . firstly , the key points of dnv fatigue assessment are addressed , and then the fatigue strength of some nodes concerned is conducted using the simplified analysis provided by dnv fatigue assessment rules . 本文以dnv疲劳评估规范为指导，以12300吨滚装船为依托，探讨了dnv疲劳评估规范中不同方法之间的差异，其主要内容包括： 1 、对dnv疲劳评估方法的要点做以说明，利用dnv疲劳评估文献提供的简化方法对感兴趣的节点进行疲劳评估。
The total target that the transportation departments do about adjusting the construction of transportation capability is keeping the shipping abilities constant and reducing to 18 percent in the dry cargo and break bulk cargo ; rise up 12 percent in oil ships ; owning 1 . 5 percent in chemical and liquid ships and 6 . 5 percent in roll - roll and other ships in 2005 . the transportation capability is controlled by the promotion of 2 . 5 pecent during 2006 and 2010 . the transportation capability is reduced to 75 percent in dry cargo and break bulk cargo and risen up 13 percent in oil ships ; 2 percent in chemical and liquid ships ; 10 percent in roll - roll container and other ships in 2010 交通部关于运力结构调整的总体目标是： 2005年前，长江省际运输运力总量基本保持不变，通过结构调整到2005年使干散货运力比重下降到18 ，油船比重上升到12 ，化学品船和液化气船占1 . 5 、汽车滚装船等其它船舶占6 . 5 ； 2006年? 2010年，长江省际运输运力总量平均增长控制在2 . 5以内，通过结构调整，到2010年使干散货船运力比重下降到75 ，油船比重上升到13 ，化学品船和液化气船占2 ，汽车滚装船、集装箱船等其它船舶占10 。
The models of ro - ro ship and vehicle on board come from the most common types on the seaway in bohai strait . the construction of the models has been based on such theories as theoretical mechanics , advanced mathematics , space analytic geometry , the theory of ship and sea - keeping theory 模型中所研究的滚装船舶和船载车辆是在渤海海峡滚装船运输生产中最为常见的类型；整个模型是建立在理论力学、高等数学、空间解析几何的基本理论和船舶原理、船舶耐波性的专业理论基础上的。
The shifting of cargo on board ro - ro ships has been identified as a contributory facter for the significant number of ro - ro ships casualties , worldwide , over the last decade . it is the focus of the discussion of imo and most ro - ro flag states when they investigated all means to enhance the safety of ro - ro ferris 但是，滚装船舶许多自身难以克服的缺陷使它在航行安全性方面无法与其经营上的优越性相提并论，其中滚装船上车辆的绑扎系固问题在造成众多滚装船海难事故原因中显得尤为尖锐突出。
At the same time , a new decision - making method which determines the indices weight on the basis of the subjective preference and objective information entropy with the strict least square method as a tool is provided in the process of mcdm . with the development of worldwide shipping market , all kinds of special ship types and corresponding ship form evaluate alternatives are emerging . the traditional ( gb11697 - 89 ) method is only suitable for common ship types and it is not suitable for ocean floating structure system evaluation either 传统的国标法( gb11697一89 )只能对散货船、集装箱船、干货和杂货船、多用途船、油船和滚装船等普通船型进行方案评价，也不能用于海洋工程中浮式结构物的系统论证，故采用gb11697一89针对上述特殊船型进行船型方案论证和技术经济指标评价显然已不能满足实际工作需求和未来船型发展方向。
