摘要
在分析零件CAD特征建模的基础上,针对零件设计和材料选择及加工参数结合松散的现状,参照生物信息学,提出了一种综合考虑材料性能参数、加工参数和几何结构的多特征零件信息模型,又基于该模型建立了多特征零件基因编码理论及其数学模型。利用该理论和算法建立了常见几何特征模型的基因编码和简单零件的基因编码,并通过CATIA5R8验证了多特征零件设计算法。
The current part structural design does not consider material choosing and manufacturing parameters, a limitation that has not been recognised in the previous work. To this end, based on the analysis of part CAD modelling, and referring to the bioinformatics knowledge, we propose a new feature-based part information model which comprehensively considers the part′s material, manufacture parameters and geometry structural parameters——as shown in Fig 1. Having proposed the model, a multi-feature part gene coding theory and its algorithm are then established. Based on such algorithm, we finally build the gene coding of general geometry feature and simple parts, and its algorithm is validated in CATIA5R8 platform.
