【摘要】：21世纪是设计的世纪,同时也是竞争的世纪,任何设计都将面临激烈的竞争,社会需要的设计是有竞争优势的设计而不是被淘汰的设计。由此,快速、高效地进行产品设计是目前设计方法学的一个重要研究领域,而虚拟油泥技术FreeForm的出现是对现有计算机辅助设计方法的一个有益补充,因此,本论文的研究对于丰富了计算机辅助设计的建模方法,特别是曲面模型、快速建模与制造一体化、快速响应市场需求与变化具有较强的应用价值。本论文在查阅国内外相关文献资料的基础上,围绕快速产品设计展开研究。首先,从虚拟油泥技术的技术构成出发,分析了虚拟油泥技术的产生、发展、繁荣及其未来的发展趋势四个阶段。将其第四个阶段即触觉式设计中的复杂曲面造型作为研究对象。通过分析虚拟现实技术、力的反馈技术、3DTouch技术及其FreeForm的操作系统,从三维建模中的线框建模、面片建模及其实体建模出发,比较了基本体构建法、视图构建法和自由雕刻法三种建模方式。分析了其概念及其特征,得出该技术的优点在复杂曲面造型设计。其次,归纳了产品曲面造型、工艺品的曲面造型、角色动漫的曲面造型及其其他特殊的产品曲面造型设计,将其划分为有规律的曲面造型和无规律的曲面造型、具象的形态造型和抽象的形态造型、规整式(折线型、直线圆弧型)的曲面造型和不规整式的曲面造型。结合了实例,详述了其建模方式,对于提升设计速度、丰富表达效果(曲面造型)、优化设计流程具有快速和方便的应用价值。最后,通过了其在各个领域的应用及其详细的作图步骤,得出了该技术有利于产品的概念设计、灵活多变的设计流程,有利于快速、高效的进行批量化生产。同时,也有利于发挥设计的设计智慧、兼顾经济和社会效益,其造型易于满足消费者对于新颖和夸张的需求,并有利于明确的市场需求、良好的商品造型化及其产业化前景。在此前研究的基础上,并着重探讨了产品的概念设计,从市场调研、功能设计、原理设计到商业设计的整个过程。不仅能创造出更人性化、更优美、更符合消费者需求的产品设计,而且有利于快速生产和快速制造。阐述了该技术能够从设计制图到模型制作再到最后的成品实现产品一条龙的生产。表明了该技术能够解决复杂曲面造型的问题和优化设计,同时,也有利于实现产品的设计创新、工艺创新、材料创新、市场创新、设备创新、生产组织和管理创新及其用户创新。
[Abstract]:The 21st century is not only the century of design, but also the century of competition. Any design will face fierce competition. Therefore, rapid and efficient product design is an important research field in current design methodology, and the emergence of FreeForm is a useful supplement to the existing CAD methods. The research in this paper has a strong application value for enriching the modeling methods of CAD, especially the surface model, the integration of rapid modeling and manufacturing, and the rapid response to market demand and change. On the basis of consulting domestic and foreign literature, this paper focuses on rapid product design. Firstly, starting from the technical composition of virtual sludge technology, four stages of virtual sludge technology are analyzed, such as the emergence, development, prosperity and future development trend of virtual sludge technology. The fourth stage is the complex surface modeling in tactile design. By analyzing virtual reality technology, force feedback technology 3DTouch technology and FreeForm operating system, this paper compares the basic volume construction method from the wire-frame modeling, facet modeling and solid modeling in 3D modeling. There are three modeling methods: view building method and free carving method. The concept and its characteristics are analyzed, and the advantages of this technology in complex surface modeling design are obtained. Secondly, the product surface modeling, handicraft surface modeling, character animation surface modeling and other special product surface modeling design are summarized, which can be divided into regular surface modeling and irregular surface modeling. Figurative shape modeling and abstract shape modeling, regular (broken line, straight arc) surface modeling and irregular surface modeling. Combined with an example, the modeling method is described in detail, which has a quick and convenient application value for improving the design speed, enriching the expression effect (curved surface modeling) and optimizing the design flow. Finally, through its application in various fields and its detailed drawing steps, it is concluded that the technology is conducive to product conceptual design, flexible design process and rapid and efficient mass production. At the same time, it is helpful to give full play to the design wisdom of design, to take into account the economic and social benefits, and its shape is easy to meet the needs of consumers for novelty and exaggeration, and is conducive to clear market demand, good commodity modelling and its industrialization prospect. On the basis of previous research, this paper discusses the whole process of product conceptual design, from market research, function design, principle design to commercial design. Not only can create a more human, more beautiful, more responsive to consumer demand product design, but also conducive to rapid production and rapid manufacturing. This technology can realize one-stop production from design drawing to model making and final product. The results show that the technology can solve the problem of complex surface modeling and optimize design. At the same time, it is also helpful to realize the product design innovation, process innovation, material innovation, market innovation and equipment innovation. Production organization and management innovation and customer innovation.
