Abstract

The invention provides an aircraft structure design method based on a parametric component, which is characterized in that the parametric component is used for expressing typical parts in an aircraft structure, the component contains geometric information and non-geometric information of the structure, and the parametric component is a three-dimensional digital model which is formed by inducting and reorganizing parts generally used in the aircraft design and contains geometric and non-geometric attribute data information. Compared with the prior art, the aircraft structure design method has the advantages and effects of contributing to standardizing a digital product definition process and laying a foundation for the realization of a unified model interacted system. The invention provides a component definition method of the typical parts of the aircraft structure and a component library system for forming an aircraft through the method, the digital product definition process is standardized, and a function and performance model data foundation is provided for the stimulation analysis and optimization of every auxiliary procedure during the aircraft design, so that the consistency of data between geometric model machines and function / performance model machines is ensured, the design quality of the aircraft is improved, and the development life-cycle is shortened.

Description

technical field

[0001] The invention relates to the technical field of aircraft structure design, and in particular provides an aircraft structure design method based on parametric components. Background technique

[0002] 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 professional design process. For thi...
