【摘要】 通过对多学科协同设计特点的分析,提出了一种融合结构数据、语义数据和协同管理数据的产品信息模型。采用一种扩展的面向对象方法来表达产品模型,并可根据需要进行多层次的继承及添加新的属性类,实现产品模型的横向和纵向扩展。基于这种产品信息模型及其表达方法,提出了一种多学科协同产品建模的系统结构,可有效地支持多学科协同地进行产品建模,并具有良好的模块性、柔性及可扩展性。更多还原

【Abstract】 Based on the analysis of the characteristics of multidisciplinary collaborative design,a product information model that merges physical structure,semantics and collaborative management data was put forward. An extended object-oriented method was introduced to represent the product model.Through the additions of new attributes and the multiple layers class inheritance,the product model can be extended transversely and lengthwise.Then,an architecture of multidisciplinary collaborative design was proposed,which can effectively support multiple disciplines for collaboratively product modeling and has good modularity,flexibility and expansibility.更多还原
