Abstract

Abstract: This paper mainly discusses how to obtain design knowledge from the finite element analyzed data.With regard to one design problem，the orthogonal experiment table is established according to diverse values of design variables，and variables in each kind of experimental schemes are built by the entity model of Pro/Engineer software and then the entity model is analyzed by ADAMS in order to obtain design parameters which satisfy design need.The data of different characteristics collected from the stress analysis and other relative computation data constitute a new two-dimensional form from which design knowledge is extracted by using the rough set theory.This method of knowledge acquisition is tested by the analysis of the data from driving head of hydraulic drill.The test shows that the method obtains three strong associate rules for the design of driving head，which is applicable.The experiments prove that this method of knowledge acquisition is correct and effective and can also be used as guidance for extracting design knowledge from other engineering analyzing software.

Key words: knowledge acquisition, ANSYS analyzed data, design for driving head, orthogonal experiment, rough set theory

摘要： 研究如何从有限元分析数据中提取设计知识的方法。对某个设计问题，依据设计变量的不同取值构建正交试验表；对正交试验表中每一种试验方案的变量取值采用Pro/E建立设计问题的实体模型；该实体模型经ADAMS动力学与运动学分析后获得满足工作要求的设计参数；依据该设计参数在ANSYS应力分析中获得设计问题的不同特征数据；并以该特征数据以及问题的相关计算数据构成新的二维表；采用粗糙集理论对二维表数据进行知识抽取。以锚杆钻机动力头设计的ANSYS分析数据抽取知识加以验证，验证结果获得了动力头设计的3条指导性强关联规则（知识），从而证明该知识获取方法是正确有效的，该方法对其他工程分析软件抽取设计知识具有很好的借鉴作用。
