基于知识工程的旋耕机刀辊的快速设计系统研究

Research on rapid design system of rotary blade roller based on knowledge engineering

为了提高旋耕机刀辊的设计效率,建立了一种基于知识工程的对旋耕机刀辊的快速设计系统:在查阅整理旋耕机刀辊设计流程及规则知识的基础上,建立刀辊参数库、规则库、实例库等知识库,选用SQL语言对知识库进行添加、查询、修改;应用基于规则和实例的混合推理方法,以SolidWorks和Visual Studio为系统开发平台,应用API二次开发工具和VB.NET语言开发刀辊的快速设计系统,实现尺寸驱动模型变更和不同农耕农艺要求下刀辊的参数化快速设计。在Intel i5处理器、系统内存8 GB配置环境下,快速设计系统运行3~5 min即可设计出满足用户需求的刀辊CAD模型并输出文件,满足使用需求。

In order to improve the design efficiency of rotary blade roller, a rapid design system was established for rotary blade roller based on knowledge engineering: On the basis of collecting the design process and the rules of the rotary blade roller, the knowledge libraries including the parameter library, rule library, and instance library have been established for the rotary blade roller, which were added, queried, and modified to the database by using SQL language. Appling a hybrid reasoning method based on RBR and CBR, a fast design platform for rotary blade roller with API secondary development tools and VB.NET language has been developed under the system development platforms of Solid Works and Visual Studio. Size-driven model changed and parameterized rapid design of the rotary blade roller have been achieved under different agricultural agronomy requirement. Under the Intel i5 processor and 8 GB system memory configuration environment, the rapid design system can be run for 3 to 5 minutes to design a CAD model of the rotary blade roller with output files under the user’s requirements, which meets the needs of application.
