【摘要】 针对并行工程对产品数据管理CAD系统提出的新要求,该文在描述产品装配模型概念的基础上,建立了产品装配模型的信息模型和数据模型,并就产品装配模型在新一代产品数据管理与CAD系统中的作用作了一定的探讨,最后通过实例说明产品装配模型的可行性与实用性。更多还原

【Abstract】 The concept of assembly model is proposed according to the new requisition for PDM(Product Data Management)and CAD-system, which is required by the concurrent engineering.Information model and data model have been con-strcted based on the product assembly model. In this paper, the effect caused by the product assembly model on the PDM and CAD -system has also been analysed,finlly,an example is given to show the feasibility and practicability of the product assembly model.更多还原
