| 摘要: |
| 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及其描述语言VPML，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”描述设计对象之间的约束关系。V-desModel模型和VPML语言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型的逼真性要求和设计信息不完备之间的矛盾，为多领域系统在概念设计阶段的协同设计、并行设计及联合仿真过程提供一致的模型描述。 |

| Abstract: |
| Considering the characteristics of conceptual design and the feature classification of virtual prototype, this paper presents a novel virtual prototype-based product model, V-desModel, and the description language, VPML, in conceptual design. It introduces virtual feature concept in the product's view models, and employs expandable 3D entity-constraint graph to describe the constraints between design objects. V-desModel and VPML language can effectively support the process of cooperative design and concurrent design, solve the insufficient information problems in constructing virtual prototype during the conceptual design of product. They provide coherent model description for cooperative design, concurrent design, and confederate simulation of multi-discipline systems. |
