基于产品基因分解重构的生长型设计

Incremental Growth Design Based on Decomposition and Reconstitution of Product Gene

将基因工程思想用于产品的进化设计过程,通过对产品基因的多级分解提出了产品组成单元的进化策略。在给出基于功能约束的产品基因分解数学模型的基础上,将装配复杂度及制造复杂度作为有效的控制约束引入其中,得出了产品基因的最优划分策略,在此基础上提出了基因重构方法。用滚子夹具设计实例验证了设计方法的有效性。

By applying genetic engineering methodology into the incremental product growth design, a generic structural design approach was put forward, as well as an intelligent evolution strategy of the product units growth, which was based on multilevel Decomposition and Reconstruction of product gene. Firstly, a functional constraint based product gene decomposition model was built up by introducing the assembly complexity and manufacture complexity into the model, as a result of the model analysis, an optimized incremental growth process of product gene was obtained. Secondly, from the optimized incremental growth process, a novel reconstruction method of product gene was developed. Finally, the conceptual design of a clamping tool was given as an example to demonstrate the contribution of this method to product principle innovation in conceptual design.
