Parameter Setting Method of Class 1 Components of Aircraft Skin Panel Parts

Abstract

A parametrization design method for aircraft skin wall panel part primary components includes that parametrization components are used for expression of skin wall panel parts in an aircraft structure, and the parametrization expression of the aircraft skin wall panel part primary components particularly relates to the following four parts of the content: 1), 'essential attribute' which particularly includes component name, version number, creation time, component description, manufacturing technique and remarks, 2), 'geometric attribute' which particularly falls into location parameters and section parameters, 3), 'non-geometric attribute' which particularly relates to scheme decomposition and 'non-geometric attribute' information corresponding to the scheme decomposition, and 4), a 'two-dimension sectional drawing' which is used for correct understanding on the physical significance of each parameter of the components by users in component instantiation. The parametrization design method for the aircraft skin wall panel part primary components facilitates the establishing of an aircraft component base system, provides function and performance model data base for aircraft design standardization and simulated analysis and optimization, guarantees the coordination and consistency of data among geometric prototypes and function prototypes / performance prototypes, improves the aircraft design quality, and shortens the aircraft development cycle.

Description

technical field [0001] The invention relates to the technical field of aircraft structure design, and in particular provides a method for setting parameters of level 1 components of aircraft skin panel parts. Background technique [0002] In the prior art, with the continuous in-depth application of CAD technology, CAD technology has increasingly become an indispensable tool for aircraft design departments. Designers need to solve the parameter determination problem before using CAD to complete the 3D solid model of the product - design. If CAD technology cannot participate in the determination of product parameters, then the application of CAD technology in design is only a description of design results, not a real design. The model construction of the design process becomes the key for the CAD system to participate in the product design process. This model should be suitable for the data requirements of CAD / CAE and other systems, and conform to the description of the pro...

Problems solved by technology

At present, CAD and CAE technology can achieve seamless integration in terms of physical analysis of parts, but how to solve the seamless integration of aerospace thin-walled structures, that is, to solve the problem of inconsistency between the geometric type of the CAE model and the geometric type of the CAE model, has become an influential factor. The key to the seamless connection between CAD and CAE cannot be solved by the existing technology
