摘要
产品设计早期的知识和设计要求是不精确和模糊的,难以形式化表示,使得概念设计活动具有挑战性.而概念设计中功能结构的确定、设计过程模型的建立及多方案生成是其技术关键.建立了产品功能结构,确定出功能参数,根据键合图基础元件建立行为矩阵模型;然后利用势流变换建立功能方法树的基本构造块,采用人工智能技术生成功能方法树,产生多方案及评价;最后结合加工中心上快速夹紧装置对其应用进行了说明.
Knowledge of all requirements and constraints during the early phase of a product design is usually imprecise, vague, and difficult to describe formally. It is crucial for the conceptual design to establish functional structure, found the process of design model, and produce multi-solutions. This paper presented functional structure of mechanical product, established functional parameters, and determined a matrix model by use of bond graph fundamental elements. Then, functional means tree was produced by effort-flow transforming operation, and multi-solution production and evaluation were utilized by artificial intelligent technique. At last, an example of the design synthesis was presented to show an application in special purpose jig device of machining center.
