A block linkage design method for the local structure of non-standard parts of customized products

Abstract

The invention discloses a block linkage design method of a customized product nonstandard part local structure. The method comprises the following steps: constructing a structure module associated constraint model according to geometric features, boundary features, positioning constraint and like information of the customized product nonstandard part local structure, dividing the structure module into a real structure module and a virtual structure module, defining that three linkage relations of connection, constraint and linkage are existent between the modules, and establishing a linkage design matrix after encoding the structure module linkage relation; extracting the structure module participating the local structure design to form a linkage design sub-matrix; reconstructing the topological relation of the nonstandard part local structure by performing three-dimensional Boolean operation and splicing on the structure module, thereby realizing the block linkage design of the customized product nonstandard part local structure. The product is customized and designed from the nonstandard part local topological structure layer, the design knowledge reusing of the structure granularity is realized, the design efficiency of the customized product is improved, and the personalized customization demand of the product can be fast responded.

Description

technical field [0001] The invention relates to a design method for a non-standard part of a customized product, in particular to a block linkage design method for a local structure of a non-standard part of a customized product. Background technique [0002] Customized products are a kind of products designed and manufactured according to orders. With the diversification of customized needs, manufacturing enterprises are faced with more and more customized product design and manufacture. How to design customized products with high efficiency, low cost and quick response to individual needs of customers has become an important issue in product design. [0003] Customized product design is essentially the design of non-standard parts. The existing customized product design methods are mainly through planning a more versatile product design platform, developing more functional modules that meet different individual needs, modular product configuration and optimized design, Th...
