机床主轴系统设计的知识模板描述与重用方法研究

Research of Knowledge Template Description and Reuse for Machine Tool Spindle System Design

针对机床企业主轴系统结构设计、有限元分析以及优化设计等过程中知识描述与重用的问题,建立了由设计经验、知识以及主轴性能影响等因素构成的主轴结构设计知识模板,提出有限元分析过程的信息模型和知识表示以及有限元分析模板创建的一般办法。构建了一种由用户定制模块、模板匹配模块、结构设计模块、有限元分析模块、优化设计模块、三维建模模块以及设计资源中心等组成的主轴智能设计系统的体系结构。在此基础上,开发了基于知识模板的主轴设计原型系统,应用实例表明,该系统有助于实现设计知识重用和快速设计的目标。

For problems of knowledge description and reuse in spindle design,finite element analysis and optimization knowledge template which was consists of design experience,knowledge for spindle design were set up.The optimal design template was constructed based on math model of spindle structure optimal design,and knowledge template was selected used fuzzy decision-making method.Then intelligent design system（IDS） based on knowledge template created.Results show that system helps to achieve goal for knowledge reuse and rapid design.
