【Abstract】: In connect with large amount of repetitive labor and poorly flexible of designed model and lack of access to the information needed for subsequent capp processes in the design process for aircraft frame ribbed parts, this paper proposes using feature-based parametric modeling method by the way of taking the secondary development of 3D modeling software SolidWorks by using visual Basic6.0, in order to establish a Interactive design and assembly system for aircraft frame rib parts. The specific design method is illustrated by an example of a typical frame rib of a fighter, and realize the size driven of the model and the intelligent assembly between the parts are realized to achieve shortened design cycle, improve parts production efficiency, and enhance design flexibility.

0 ?引言
飛機框肋零件作為飛機主要結構件其總量約占一架殲擊機零件總數的30%,其結構相對簡單但類型多變,傳統建模方式主要為手工繪制或者通過對三維造型軟件的完全編程式的二次開發,設計人員需要進行大量的重復勞動,且模型信息不能有效的傳遞至下游生產加工階段,不僅增大成本更延長生產周期,降低產品生產效率,使企業競爭力下降不利于現代化企業轉型與發展[1]。
為解決上述問題,以特征建模為基礎,結合參數化尺寸驅動設計方法,將尺寸、約束變量化[2],并利用三維特征建模軟件SolidWorks對某殲擊機典型框肋件進行三維建模,采用VB程序設計語言搭建可視化人機交互平臺,最終實現對飛機框肋零件模型的自動化建模以及零件間的智能裝配。……
