基于案例结构检索的液压CAD系统设计与开发

Development of CAD System of Hydraulic Based on Case-based Reasoning

在研究国内外液压系统CAD辅助设计现状的基础上,利用案例推理技术,设计以结构检索为主、属性检索为辅的平台。重点介绍了使用案例的步骤、案例存储和案例检索的机制,并和液压CAD系统的产品信息模型有效结合成一体。案例能够有效地指导设计工作,并且促使系统性能向技术要求逼近。实验证明,案例推理的方法对于液压系统这种高阶、难仿真系统有良好的辅助设计作用。

Acquainted with domestic and international researching status of Case-based Reasoning and CAD, this paper tries to explain a software platform, which is helpful to design hydraulic system based on a good-working case. There are four points： How the good case helps people to design, how these cases are stored and how the proper case is found out, and how the information model of hydraulic system product is managed. Thus, these cases can guide, and make the design closer to the demand. It is sure that the case-based Reasoning is helpful to design hydraulic system, which often is high-level and difficult to simulate.
