摘要:
根据机床组件有限元分析特点,结合人工智能和有限元商业软件ANSYS,建立了针对机床组件有限元前处理过程的专家系统.首先根据有限元软件的操作流程对专家系统的运行流程进行了设计.通过对专家经验、理论知识、设计手册等知识的搜集和分类,运用基于逻辑的规则知识表达模型,将其转换为专家系统知识库中的知识,对有限元前处理知识和结构化知识做了较为详细的描述.同时也对专家系统中知识的推理和计算过程以及知识库的动态更新过程进行了讨论.最后利用机床主轴挠度分析作为实例,进一步讨论和证明了该系统的适应性和可靠性.
Abstract:
According to the characters of FEA(finite element analysis)for machine tool’s component and integrated with AI(artificial intelligent)and finite element software ANSYS, the expert system is built for finite element analysis of machine tool’s components. The flow of expert system is designed following finite element software. The knowledge from the experts’ experience, theories knowledge, and design handbook are collected and categorized. The logic-based knowledge model is adopted to express the knowledge of the expert system. Especially, the pre-process knowledge and the structural knowledge are described in detail. The reasoning and computing process of knowledge in expert system and the dynamic updating of database are discussed. Finally, an example about spindle’s flexibility analysis is illustrated to prove the effectiveness and reliability of the system.
