汽车发动机缸套活塞环设计专家系统的研究与实现

Realization of An Expert System for Automobile Engtnes'Cyinder Bore and Piston Rings Design

针对机械设计中逻辑推理和数值计算交织在一起的特点，本文对所研制的用于汽车发动机缸套活塞环设计的专家系统的实现进行了讨论，其中包括：设计型专家系统知识表示的形式，“设计一评价一再设计”求解策略和“分层计划”推理控制机制。实现了的系统表明：本文所用的理论或方法能较好地解决复杂的机械设计问题。

According to the feature of alternating logie arsumentation with numerical calculation in the pro-ess of niechanical deeign,a discussion in this paper is prxsented about the realization of an expert sysstem for automobile engines'cylinder bore and piston rings desisn,including:rule forms of knowledgeepresentation to use engineering desisn,solving tactics of ii design-evaluate-redesign'and control mechnisni of',hisrarchy plan'.The impleniented system shows that the thcory as well as the methods pre-znted in this paper can serve the mechanical desisn problems quite well.
