基于数据库技术和模块化设计方法,采用产生式规则知识表示方式,将耐磨材料的大量相关数据、专家经验知识和选材准则构成知识库,设计了耐磨材料选材专家系统整体框架.实现了对耐磨材料的信息存储、快速查询等功能.运用现代选材方法,通过简单判断、典型零件选材、综合选材和目标选材进行定性、定量选材并作出评价,对耐磨材料的使用及生产工艺的制定、新材料的开发等方面提供依据和指导.

Based on database technology and designing method of modularization,adopting production rules to express knowledge,database knowledge with a large amount of data of wear resistant materials,experience knowledge of expert and principle of materials selection had been established,the whole frame of the materials selection expert system of wear resistant materials had been designed.The system realized store and inquiring of wear resistant materials quickly.By simple judgment,materials selection of typical part machining models,using modern method of generalization,and goal,materials selection,the system provides scientific evidence and technological guidance for wear resistant material using,production and development of new material.
