Modeling for standard components of aircraft assembly fixtures

According to the structural characteristics of standard components of aircraft assembly fixtures, this paper presents a new technique for modeling and managing these standard components. The techniques for managing standard components are reviewed. On the basis of analyzing the standard component information, standard information model, structural and shape model, and semantic management model are proposed. The algorithm of interpreting the semantic management model is created. Compared with other methods, this modeling technique for standard components has several advantages, such as using data model and generalized program and being convenient to maintain. This technique can be also applied to manage typical structures of fixtures and their components.
