【摘要】 虚拟现实技术是利用计算机生成一种高逼真的模拟环境，通过多种传感器接口，使用户“沉浸”到该环境当中，实现用户与该环境直接进行“交互”的技术。随着虚拟现实技术和计算机图形处理能力的迅速发展，将虚拟现实技术运用于制造领域已经成为可能。国内外已经有许多成功的应用实例。 本文将虚拟现实技术运用到灌装生产线的设计中，真实的反映现实生产线中各主机的运作，物流的变化、人员的安放等实际情况，再现车间现场环境，从而给企业和客户提供一个方便快捷的信息交流平台，一种直接、形象的技术方案交流手段，可以对技改方案进行技术和经济分析；同时，还能够解决生产线上存在的一些实际问题。这种设计方法给传统的灌装线设计提供了新的手段。 本论文结合广东轻工机械集团课题“灌装生产线三维布置虚拟仿真系统”和广东省科技厅的课题“虚拟环境下生产线设备三维动态布置的关键技术研究”，在Visual C++平台上，使用MFC和WTK，通过开发基于PC的虚拟灌装生产线的例子，研究了以下几个内容： 1．在分析传统灌装线设计的基础上，指出了存在的不足；提出了灌装线虚拟设计的基本任务；确定了虚拟制造生产线的设计原则和设计框架。 2．对灌装机各项基本参数设计计算，指出影响灌装机生产能力的各项因素。 3．利用面向对象的思想对灌装生产线对象分类，提出基于OPE(Object/Property/Event)机制的虚拟环境对象行为控制理论，并将其应用在虚拟生产线设计当中。 4．研究虚拟现实系统中的各种建模方式，结合虚拟现实开发工具包WTK(WorldToolKit) 分析各种建模的特点，并对灌装线中的两种主机：灌装机和洗瓶机进行了建模与仿真。 5．分析了虚拟路径的构成原理，设计虚拟漫游系统来浏览虚拟生产线；提出虚拟设备管理的思想，使设计人员对设备的工作情况一目了然。 最后，本文针对系统开发中的工作与体会做出了总结，并对基于PC的虚拟生产线仿真系统的应用前景做出了展望，为后续的研究开发工作提供了参考。更多还原

【Abstract】 The Virtual Reality technology is a technology that produces a highly vivid simulation environment by using computer to make user immense into the virtual environment by some kinds of sensor interfaces and accomplish interaction between user and environment. With the rapid development of the Virtual Reality technology and the imagine manipulation capacity of the computer it has become possible to apply the Virtual Reality technology into manufacturing fields. There have already been many successful examples of application about that at home or abroad.This article applies the Virtual Reality technology into designing the beverage-packaging production line, which truly reflects actual conditions in the production line such as the operation of every host machine, the motion of the material flow, the deployment of personnel and so on, and recur the workshop locale, consequently provide a convenient and quick platform and a direct and vivid way to technical intercommunion that can provide technical and economical analyses to technical emendation for enterprises and clients as well as solve some actual problems in the product line. This method put forwards a new way to design the traditional beverage-packaging production line.Combining the project of Guangdong Light Industry Mechanics Group "the three-dimensional dynamic visual simulative system of the beverage-packaging production line" and the project of Guangdong Science and Technology Bureau "the research of the key technology of three-dimensional dynamic deployment about product line devices in virtual environment", this dissertation investigates the following contents through developing an example of the visual beverage-packaging production line based on PC by using MFC and WTK(World Tool Kit)with visual C++.1.On the basis of analyzing the traditional beverage-packaging production line, point out some shortcoming in it, put forward the basic task of designing the virtual beverage-packaging production line, and establish the design rule and design frame of virtual manufacturing production line.2.Design and calculate the basic parameters of the filling machine, and point outthe factors affecting the throughput of the beverage-packaging production line.3. Class the objects in beverage-packaging production line by using object-orientated idea, put forward the Object Action Control Theory in virtual environment, and apply it into the design of the virtual production line.4. Research various kinds of modeling ways in virtual reality, analyze the characters of every kind of modeling way with the developing toolkit WTK in virtual environment, and make a modeling and simulation about the filler and washer in the production line.5. Research the composing rule of virtual path, design a virtual walkthrough system to browse the host machine in virtual environment; put forward the idea to manage the devices in beverage-packaging production line and can let designers understand explicitly the devices condition in production line.Finally, this dissertation sum up the work and experience in system development and offer the reference for following development works.更多还原
