利用功能表面来形式化表达产品基因以支持机械产品概念创新设计。用数学方法描述了功能表面模型和产品基因模型,提出了一种变长度的产品基因层次编码方案,构建了基于功能表面的产品基因形式化表达过程,并用设计实例对提出的方法进行了验证。
In order to support the conceptual ereative design of mechanical products, functional surface is used to express product gene formally. Functional surface model and product gene model were described mathematically, a product gene coding scheme with varied length and multilevel was proposed, the product gene formalization process based on functional surface was created and a design example was used to demonstrate the proposed method.
