摘要当今社会由于船舶的普及，各行各业都用到了船舶，这使船舶运动的安全性和效率被我们广泛的关注和重视，然而船舶运动数学模型又比较复杂，研究起来需要花费大量的时间个精力。本文根据单机仿真技术，设计出了船舶运动仿真系统，旨在协助我们了解船舶运动的各个特性，从而降低了船舶技术的开发时间，也可以给我们提供更直观、有效的实验环境。

本次的课题为船舶运动仿真系统设计，通过了解船舶模型、环境模型和系统设计的相关资料，运用Labview对该系统进行设计并且实现。本次设计的仿真系统包括：模型模块、显示模块及存储模块的设计。具体内容如下：86022

（1）船舶运动仿真的数学模型，本文从船舶运动方程和船舶运动动力学方程的研究分析，加入风、浪、流三种环境干扰因素，建立船舶运动的三自由度运动模型。实现只需输入相关船舶、环境参数，从而得到我们需要的数学模型。

（2）船舶运动仿真的显示模型，这个模块主要以Labview中的显示控件实现，通过波形、三维图片控件，实现对船舶实时的运动轨迹、运动姿态、速度以及船舶在海中运动时所受干扰力的显示。从而让我们更直接的观察到船舶仿真运动时的过程。

（3）船舶运动仿真的存储模块，运用Labview中的存储空间，来实现对船舶运动的坐标的存储。

建立船舶运动仿真系统的船舶运动模型和环境模型，实现船舶运动轨迹、船舶运动姿态的显示以及坐标的转换，使初学者更可以简单的观察船舶运动的特点并进行研究分析。

Abstract

In nowadays, ship is used in all trades and professions which makes the safety and efficiency of ship motion be our extensive concern and attention。 But ship motion mathematical model is very complex, so the study of it needs to spend lots of time and energy。 According to the computer simulation technology, this paper designs the ship motion simulation system in order to help us to understand the various characteristics of ship motion, thereby reducing the ship technology development time。 In addition, it can offer us a more intuitive and effective experimental environment。 

The theme of this paper is ship motion simulation system design。 Through understanding the ship model, environmental model and system design of the relevant information, Labview is used to design and implement the system。 The design includes: model module, display module and storage module。 Specific contents are as follows:

⑴ Simulation of ship motion mathematical model。 This paper which adds three environmental interference factors including wind, wave and streams, establishes ship motion model from the study of the equation of ship motion and analysis with wind and wave of dynamic equations of ship motion with three degrees of freedom。 When inputting relevant ship environment parameters, we could get mathematical model we need。

⑵ The ship motion simulation display model。 This module is displayed by Labview。 Through studying the waveform and three-dimensional picture control, we could understand the real-time trajectory, movement posture, speed as well as the display of ship in the sea disturbing force。 So we can observe the ship motion simulation process。

⑶ The storage module of the ship motion simulation。 This module uses the storage space in Labview to achieve the coordinate of the ship motion storage。

 By establishing ship motion and the environment model of ship motion simulation system, the ship trajectory, the display of ship movement posture and coordinate conversion can be achieved。 Even beginners can observe characteristics of ship motion more simply and analyze or research it deeply。
