Problems solved by technology

When designing new products based on order requirements, most manufacturing companies currently organize the design process and carry out product design based on the designer’s experience. There are deficiencies in the reuse of design knowledge and the rationality of the organization of the design process, resulting in repeated design revisions. Many, low efficiency, difficult to control the quality and cost of product design

Abstract

The invention relates to a meta-model-based complex product digital prototype generative design method. Comprising the following steps: S1, standardizing a design process; s2, generating a CAD digital prototype based on a meta-model; s3, generating a CAE digital prototype based on attribute extraction; s4, generating a CAM digital prototype based on MBD; according to the complex product digital prototype generative design method provided by the invention, uniqueness, consistency, reusability and integration of complex product customer demands in a product full life cycle stage are ensured, sharing, integration and application of complex equipment demand information are facilitated, and demand-driven rapid design of complex products is realized.

Description

technical field [0001] The invention belongs to the field of computer-aided design, in particular to a meta-model-based generative design method for a digital prototype of a complex product. Background technique [0002] As the demand for complex products becomes more and more variable and the product operating environment becomes more and more complex, the complex product market has evolved from a traditional relatively stable type to a dynamic and variable type, and the manufacturing industry of complex products (such as rail transit vehicles) has changed from mass production. Shift to mass customization. When designing new products for order requirements, most manufacturing companies currently organize the design process and carry out product design based on the designer's experience. There are deficiencies in the reuse of design knowledge and the rationality of the organization of the design process, resulting in repeated design revisions. It is difficult to control the...
