面向机构运动方案设计的CBR关键技术研究

The study of the key technology of CBR in the design of mechanism kinetic scheme

简述了 CBR的基本原理。根据机构运动方案设计的基本原理 ,提出从功能的角度对机构运动方案进行分类 ,运用 CBR技术解决机构运动初始方案的选择问题。采用两级实例的描述模型 ,用框架作为机构运动方案实例的描述手段。比较详细的叙述了实例检索模型的建立及基于模糊优先比的相似实例检索过程。

This paper describes simply the principle of CBR, claims that mechanism kinetic scheme can be classified according to the function and solves the selection of mechanism initialization kinetic scheme by CBR. The case of mechanism kinetic scheme is described with frame, by using two-level cases model. The formation of retrieval model and the course of similar cases index based on fuzzy priority ratio is described in detail. The similar cases are overwritten with the strategy of transpositional scheme.
