[Abstract]:Aircraft assembly frame design is an important link in aircraft process equipment design. Because of the complex structure of the assembly frame, the design frame needs a lot of knowledge and experience. In order to improve the efficiency of the design of aircraft assembly frame, this paper studies the related technology of aircraft assembly frame design and develops a rapid design system for aircraft assembly frame according to the actual requirements of a large aviation enterprise cooperation project. The main work of this paper is as follows: 1) the acquisition and integration of assembly frame design knowledge are studied, and the methods of CAA-based development and knowledge engineering are adopted. The general structure design module of assembly frame based on case knowledge is developed. The geometric design feature mapping mechanism is used to realize the feature transfer from the aircraft product design feature to the assembly frame board part design feature, which provides technical support for the parallel work of aircraft product design and assembly frame design. A parameterized component library system for aircraft assembly frame is developed, which can effectively manage the common components in the process of aircraft design, improve the design efficiency of commonly used frame assemblies, and improve the reusability of the design. In this paper, the rapid assembly technology of the assembly is researched and explored, and the assembly technology based on geometric assembly features is adopted. The rapid assembly of some typical structural components is realized in the digital design process of aircraft tooling.
