摘要
绝大多数的工业设计属于变型设计,而基于CBR技术能够有效的解决变型设计中设计重用所面临的难题。对CBR相关理论及技术进行了分析介绍,对基于CBR的精密播种机数字化设计的具体实现进行了设计研究,提出了一种新的检索算法——基于树的最近邻居法,使实例的检索更准确、高效。以铲式玉米精密播种机为例,对设计过程的实现及推理效率和准确性方面进行实验分析,实验结果表明了将CBR应用于设计问题中的可行性及优势。
Most of the industrial design belongs to variant design, the CBR-based technology can effectively solve the problem which facing with the reuse design in variant design. First, CBR related theory and techniques are introduced. Second, a design study on the specific implementation of the CBR-based digital design for precision planter, propose a new retrieval algorithm-nearest neighbor algo- rithm based on k-d tree which will be more accurate and efficient, and, take the precision planter for example, experimental analysis of the design process＇ realize, reasoning efficiency and accuracy, shows the feasibility and advantages of the CBR of application in the design problem.
