Abstract


Resin-based composite material as the representative of modern composite materials, has been widely used in industrial fields and in people's daily lives. But the design process of the composite components exist with traditional metal component design is very different influencing factors need to be taken semi-empirical design methods and design features of the building block test verification method. To take full advantage of the excellent performance of the composite components must be on its in-depth analysis of the design method, thus giving a reasonable approach their design work more intelligently. In this paper, the case-based reasoning technology applied to the resin matrix composite components design, home and abroad based on the basis of the status of the case-based reasoning system, and composite component design software, case-based reasoning resin-based composite component design method. This paper studies the work are as follows: the building block design test verification method for composite components, combined with the general design process, the composite component instance-based design methodology, and given the overall framework of the composite component instance-based design system . Composite component instance object classification and characteristics of the object model different from the traditional knowledge of the object model, and use this model instance object expression gives a method of constructing composite component instance so that the instance library You can be expanded. Study the index structure of the composite component instance, and according to the level of the index structure and content retrieval algorithm based on the similarity of the composite component instance. The algorithm is based on the instance index structure instance library initial screening, and then the selected instance library using the nearest neighbor algorithm further design similar condition attributes, and then retrieve the similar design examples provide a reference for the new design. Simulation analysis of the characteristics of the analysis of multi-level verification for composite components, and to study the mechanical properties of the composite monolayer forecasting methods the laminated plates allowable value forecast finite element method, and device simulation analysis, and given its calculation model and analysis of the model. Determine a composite component mechanical properties forecasting and simulation analysis of the results of the evaluation by the forecast or test results compare with, to evaluate the feasibility of the design results. Based on the above theories and methods of the study, and the design method of composite components for the programming language VC SQL Server 2000 database support system, CATIA, ABAQUS and ANSYS CAD technology platform, the development of a prototype system in a Windows XP environment , which validated the feasibility of the technology.
