【摘要】 近年来,随着计算机图形学,可视化技术,软件工程,硬件设计及控制工程的迅速发展,虚拟现实技术的应用也越来越广泛,它大大改变了人与计算机之间的交互方式。在这种情况下产生了虚拟制造技术,而虚拟装配是虚拟制造技术的一个重要组成部分,也是虚拟制造的关键因素之一。虚拟装配设计是产品设计的重要环节,它可以为企业带来众多的经济效益,例如缩短产品的开发周期,提高产品的质量和可靠性,降低生产成本和减少库存等。本论文对虚拟装配的设计和关键技术进行了研究,包括产品的三维建模、装配的信息、装配规划、碰撞检测技术及可制造装配性综合评价等方面内容。详细研究了装配规划中的零部件约束问题,并利用零部件在三维空间的位姿运动的矩阵及其变换矩阵和空间自由度解决零部件的拆、装问题。使用的建模软件Pro/E不同于以往的三维建模软件,是基于特征的参数化建模软件,对于零部件的一些基本特征修改方便、简洁。VRML以其优良的跨平台和易于传输特性,为虚拟装配的并行设计和协同设计提供了新的契机,用VRML语言和Java语言构建虚拟装配的交互环境来达到产品零部件的动态拆装,并最终生成虚拟样机。并以分油机为例实现产品的虚拟装配。更多还原

【Abstract】 In recent years, with the development of computer graphics, visual technology, software engineering, hardware design and control engineering, the application of the visual simulation technology is becoming more and more extensive. It greatly enhances the exchange mode between man and computer. Visual simulation assembly technology is not only one important part of the visual manufacture technology(VMT), but also one of the key factors of the VMT.Visual simulation assembly design is a very important step of the design of the product. It brings numerous economic benefits for our enterprises, for example, it enhances the quality and reliability of the products, reduces the production costs and lessens the stock.The design and key technology of the visual assembly is discussed in this dissertation, including the three-dimension modeling of the products, assembly information, the assembly layout, the collision check and inspection technology and the synthetic evaluation of the manufacturing assembly, and etc. This dissertation studies, in detail, the problem of restriction of the assembly layout, and with the application of three-dimensional position movement matrix of the parts and the matrix and of the transformation problem space freedom degree, it also discusses the problems of disassembly and installation of the parts. The software Pro/E used in this dissertation is different from the former three-dimensional modeling software. Pro/E is a parameterized modeling software based on the character of the parts. With Pro/E software, it is convenient to alter some basic characteristic of the machinery parts. VRML provides a new chance for the parallel and cooperated designing with its excellent character of easy transmission. With VRML and the Java language, this dissertation constructs the alternant environment of the virtual assembly for the purpose of dynamic installation and creation of the virtual sample machine. This dissertation also takes the purifier as an example to realize the virtual assembly of the products.更多还原
