| 摘要: |
| 传统的概念设计方法由于缺乏真实感的交互手段,难以直观表达设计者的意图.基于虚拟原型的概念设计不仅能为设计者提供逼真的虚拟设计环境,而且充分体现了现代设计的成本低、周期短以及灵活性强等特点.针对概念设计的特点以及虚拟原型的特征分类,提出了基于虚拟原型的概念设计模型V-desModel,其核心是利用产品视图模型描述设计对象,将虚拟特征概念融入视图模型中,并采用可扩展"三维实体-约束图"来描述设计对象之间的约束关系.V-desModel模型能有效地支持基于虚拟原型的概念设计过程,较好地解决了概念设计中产品虚拟原 |

| Abstract: |
| Traditional conceptual design methods cannot express designers intent directly because of the lacking of 3D interface mechanisms. Conceptual design based on virtual prototype can not only provide a 3D virtual design environment, but also meet the needs of low costs, short cycle and flexibility of modern design. Considering the characteristics of conceptual design and the feature classification of virtual prototype, a novel virtual prototype-based product model V-desModel in conceptual design is presented in this paper.It introduces virtual feature concept in product's view models,and employs expandable 3D entity-constraint graph to describe the constraints between design objects.V-desModel can effectively support the process of cooperative design and concurrent design.By employing the concept of virtual feature and method of virtual feature generation,V-desModel can solve the insufficient information problems in constructing virtual prototype during the conceptual design of product.It can not only expangd the means and ranges of conceptual design,but also be beneficial for the exertion of creativtity during conceptual design. |
