本文主要介绍了缸套、活塞环摩擦学设计专家系统的设计与建立。针对摩擦学设计过程的的特点,提出了一套设计知识的表达方法,提出了产生部分解——测试——分析修改或扩充部分解的推理控制策略。在失败处理中引入了建议指导的最小回潮策略。在此基础上,在微机上实现了缸套、活塞环摩擦学设计专家系统GYL—RING。 This article mainly introduces the design and establishment of expert system of tribology design of cylinder liner and piston ring. Aiming at the characteristics of tribological design process, a set of expression method of design knowledge is proposed and an inference control strategy is proposed to generate partial solution - test - analysis and modify or expand partial solution. In the failure to deal with the introduction of the proposed guidance of the minimum re-introduction of the strategy. On this basis, the GYL-RING, a piston-ring tribological design expert system, is realized on the microcomputer.
