    摘要:

    針對傳統(tǒng)CAD系統(tǒng)對機械產品概念設計過程支持不足的問題,提出了基于功能表面分解與重構的概念設計過程模型,。模型包括功能層,、功能表面層和結構層,。通過引入功能表面作為功能和結構的信息載體,,建立了功能,、功能表面,、結構之間的映射機制,,實現(xiàn)了功能到結構的穩(wěn)定映射關系,有利于開發(fā)計算機輔助工具來支持概念設計,。以數(shù)控銑床為例驗證了提出的過程模型,。

    Abstract:

    Traditional computer-aided design (CAD) systems are insufficient to support the upstream conceptual design process of mechanical products. A process model for conceptual design based on functional surface decomposition and reconstitution was proposed. The model consisted of three layers: function layer, functional surface layer and form layer. The mapping mechanism among function, functional surface and form was created and the steady mapping relationship from function to form was realized by introducing functional surface as the functional and structural information carrier. It is helpful in developing the computer-aided tools to support conceptual design. A numerical controlled milling machine was applied to demonstrate the proposed process model. 
