摘要随着陆地资源的日益枯竭，国与国之间对资源的开发与争夺日愈激烈。人们开始着眼于大约占据地球一半面积的海洋。近年来世界的航运市场发展迅猛，伴随了大量增加的油类、散货、集装箱的运输量，船舶大型化的趋向越发显著。船舶现阶段的发展越加复杂化、大型化，这些条件都使得港口内系泊着的船舶的运动对港口的设计十分有参考价值。停靠的系泊着的船舶因为外界不可抗因素，例如风浪等，会产生摇荡运动。系泊船舶的运动响应程度在货物装卸载时会对其产生有着很大的影响，当遇到系泊船舶的系缆力超过规定范围，在这种情况下还会发生断缆现象，这时，系泊着的船舶和码头结构安全都会受到威胁。因此，深入研究系泊船舶的运动响应不是没有理由的。80609

这类问题相对复杂，目前面对此问题时，主要可以采用物理模型和数值计算两种试验手段来对实际工程状况进行模拟，并得到所需参数，为实际工程的系泊和装卸提供条件。国内比较倾向于选择物理模型研究，数值模拟并不多见，而国外则常选择使用数模进行分析。本文利用ANSYS-AQWA软件，对船舶的水动力性能和系泊形式进行研究。首先利用ANSYS软件进行船舶的有限元建模，然后运用AQWA对其水动力性能进行性能分析，比较不同水深和入射角度对船舶水动力性能的影响。接着研究船舶在风浪流联合作用下的六个自由度运动响应和相应的系泊缆张力的情况。最后对其时域耦合做出分析，探讨结果。

Abstract As the land resource have been increasingly limited, the development and competition for resources between countries is becoming intenser。 People begin to focus on the sea which accounts for about half the size of the earth。 World shipping market is developing rapidly in recent years, accompanied by a large increase of oil, bulk, container transport, ship's large-scale trend is more and more obviously。 The complication and larger trend of ships make the movement of mooring ships becoming a important issue in the design and use of the port。 When the ship which is mooring in the wharf suffers the waves or other external factors, the degree of motion response to the mooring ship will have a big influence to the loading or unloading of goods, in case of mooring ship's mooring force is too large, it may make the line broken, even if the situation is serious, it may threaten to the safety of the structure of mooring ships and ports。 Therefore, the study of the dock before mooring ship motion responses is very necessaryly。

This kind of problem is relatively complex。 When facing this problem, the two main kinds of test，which can be used to simulate the actual engineering conditions，are physical model and numerical calculation, then we can get the needed parameters and provide practical for engineering mooring's loading and unloading。 Our country tend to choose physical model research, numerical simulation is not that common, while other countries abroad often choose to use a mathematical model for analysis。 In this paper, I will use  ANSYS-AQWA to study the hydrodynamic performance of ship and mooring form。 At first, by using ANSYS software for finite element modeling of the vessel, then I'll use AQWA to performance analysis of its hydrodynamic performance, compar them in different water depth and incidence Angle，analysis the influence of the hydrodynamic performance of the ship。 Then study the ship's six degree of freedom motion responses and mooring line tension which is under the joint action of waves flow。

Keywords: mooring at the dock; hydrodynamic performance; coupling in the time domain
