A Study of Knowledge Model Supporting Rolling Stock Rapid Design

Abstract

Abstract:

In order to meet the demands of rapid design,design processes using for organizing design knowledge were constructed on the basis of design knowledge analyzing. Starting from design constraints and design processes,using key words and design parameter matching,based on the relations among knowledges,engineers were obtained comprehensive,personalized design knowledge and appropriate CAD models.New design process for knowledge reusing was established based upon the

knowledge model to gear rapid design requirements. In the end, an example was given to testify the effectiveness of the knowledge model.

Key words:

rapid design, design process, knowledge model, model retrieval

摘要：

为了适应快速设计的需求,在对设计知识进行分析的基础上构建了用于组织设计知识的设计流程;从设计约束、设计流程出发，以设计知识间的关联为基础，分别利用关键词匹配和模型设计参数值匹配的方式，向设计人员提供全面的设计工具与参考知识集和模型集，并实现个性化的提供方式;在此知识模型基础上建立面向重用的设计过程模型，以适应快速设计的需要。某铁路货车企业快速设计系统中的验证结果表明,该知识模型能有效地为产品快速设计提供设计知识。
