摘要

摘要: 飞机制造工装中存在大量配套结构，其中各元件在空间方位和结构尺寸等方面具有严格的关联关系，但这些元件并不总是构成一个完整的组合件，而是独立隶属于工装总体结构.现有的配套结构建模技术需要繁琐的人工操作，为了实现这类结构的自动建模，提出了基于结构关联关系的虚配件技术.首先，根据配套结构的构成元件间的依赖关系引入虚配件的概念，并以此为基础对配套结构进行了形式化定义和表示；其次，研究和建立了配套结构自动建模原理，并对其中涉及的语义模型解释、文档创建及子件安装等关键算法进行了详细说明；最后，通过V形块组件结构实例测试，验证了所提方法的正确性和有效性.

Abstract: Tightly correlative structures are widely used in aircraft manufacturing tooling, elements which constitute them have rigorous correlations in the spatial orientation and structural dimensions, but sometimes they do not constitute a complete assembly as independent part of the overall structure attached to the tooling. Tedious manual operations are needed to model these structures by existing techniques. In order to realize automatic modeling for these structures, a technique of virtual assembly parts was proposed, based on associated relation in structure. Firstly, concept of virtual assembly parts was introduced on the basis of the dependencies of elements which constitute tightly correlative structures, and applied to formally define and represent tightly correlative structure. Secondly, the principle of automatic modeling of these structures was established, and the key algorithms involved such as semantic model interpretation, document creation and sub-parts mounting were elaborated. Finally, V-block assembly structure example was given to illustrate the validity and effectiveness of the approach.
