PC-process of analyzing and synthesizing friction units using databases and expert systems

摘要

A PC-process of calculating and designing units using the database (DB) and expert systems (ES) is proposed. The DB structure includes the names (brands), parameters of process treatment, volume and surface characteristics of materials to be used in friction units, characteristics of testing equipment, conditions and results of experiments, etc., as well as a variety of auxiliary data necessary for designers. Expert systems of two types are used: "common" systems comprising the knowledge base (KB) based on the rules, an interpreter block, an interface portion, and a hybrid ES which, in addition, contain the blocks for performing calculations using traditional methods of programming. The system combining the described DB and ES can operate in three major modes: data input and processing; determination of characteristics of a specified friction unit; optimal designing of a tribosystem. The above PC-process is projected to be used for designing friction units of transport vehicles at designing organizations and for taming students majoring in "triboengineering".
