【摘要】 分油机广泛地应用于现代工程领域的各个方面,特别是在船舶上,分油机是燃油和滑油系统必不可少的专用设备。所以了解分油机的工作原理、熟悉它的关键部件以及相应的故障维修,是保证船舶航行安全的重要条件。本文结合计算机仿真技术及虚拟现实理论,清晰地表达了分油机的工作原理,并以三维的方式显示它的部件信息及零件拆装。另外,通过程序还可以在底层直接引用仿真数据实现三维模型的控制。本文首先介绍了分油机仿真实现,简单的模拟分油机工作原理,并设置了一些常见的故障。通过分析故障原因,有目的地拆装分油机。本文的重点是研究解决分油机虚拟现实的两种实现方法,分析这两种方法的实现原理,各自的优缺点,并做出相应的案例。(1)基于DirectX3D的虚拟现实实现。这是以底层编程的方式实现的。基于Microsoft Visual Studio.NET 2005和DirectX图形库实现了分油机虚拟拆装。期间,充分运用DirectX提供的API,直接访问硬件设备,通过变换矩阵等方式实现对三维模型的控制。(2)基于EON的虚拟现实实现。这是直接采用高级平台方式实现的。充分利用EON程序开发的便利性,借助系统提供的功能节点以及自定义开发的功能节点,实现分油机模型拆装。对于分油机主要部件及其关键动作,还有文字、动画相关演示说明,突出表达了分油机工作原理。并且借助实验室全套硬件设备,实现了分油机虚拟现实。另外,依据对实验室分油机的实际拆装,本文采用Solidworks建立了分油机的精确比例模型;并且通过3DS Max软件实现模型优化以及重要装配关系的设置。模型的建立与优化是整个虚拟现实实现的基础。本文重点是实现了基于DirectX3D与EON这两种实现方法的研究,采用低级和高级这两种程序设计完成本文。更多还原

【Abstract】 Separator are used widely in all aspects of the modern engineering field. Especially in the ship, the Separator is special equipment that is indispensable to Fuel Oil systems and Lubricating Oil System. Therefore, we should understand the operating principle of separator, be familiar with its key components and the corresponding fault maintenance.All of these play important roles in the voyage safety. This paper associate Computer Simulation and Virtual Reality theory, which clearly expresses the separator operating principle and components information by the three-dimensional shows.Besides, the program can also directly invoke simulation data to achieve the control of three-dimensional model in the bottom.This paper firstly introduce the achievement of separator simulation, by which it simulates the operating principle of separator .At the same time,the simulation system also sets up several common malfunction. Secondly, by analyzing malfunction causes, we can dismantle the separator with destination. It is the focus of this paper to study and search the Virtual Reality of separator with two methods.It is also an important point to analysis the two methods of achieving this principle, and their respective advantages and disadvantages.And then this arcle gives the correlative case.(1) Virtual Reality based on DirectX3D.This is achieved by underlying programming.Based on the Microsoft Visual Studio. NET 2005 and DirectX graphics library,the paper achieves the virtual dismantling of separator. At the same time, making full use of APIs provided by DirectX, accessing the hardware equipment, this paper realize the control of 3D model by transformation matrix, light, material and other means.(2) Virtual Reality based on the EON.This is achieved by advanced platform.EON developers taking full advantage of the convenience of using the system-provided function nodes and user-defined development of function nodes, achieve the separator model dismantling. For the main components of the separator and key actions, there are some charater and flash demonstrations to express the operating principle of separator. Using the full set of laboratory hardware equipment, achieve the Virtual Reality. In addition, based on the actual dismantling of the separator, this paper adopts Solidworks to establish the exact proportion model.Then optimizes the model and sets the some important assembly relations through 3DS Max software.Establishment and optimization of the model is the Virtual Reality foundation.It is the most important content of this article to achieve the Virtual Reality based on two methods of EON and DirectX3D.And the paper is accomplished via both low-level and high-level programming design.更多还原
