摘　　要：如何建立维修性设计支持模块是维修性CAD平台技术面临的核心问题。根据维修性设计的特点深入研究了维修性设计支持模块的设计集成方法,构建了包含信息获取层、知识推理层、指导应用层的模块层次化模型,并详细论述了模块各层次的实现方法。通过研究设计支持模块中维修性设计信息的组织表示问题,提出了基于维修性信息结点结构的推理方法。最后通过VB和COM编程形成了基于CATIA软件的维修性CAD平台,实现了机架、箱体类零件的维修性辅助设计支持功能。The major problem of maintainability design CAD platform is how to establish maintainability design support module.According to the characters of maintainability design,integrated design method of the module is deeply studied,and hierarchical model of the module is constructed,which includes information acquisition layer,knowledge reasoning layer and application guiding layer.Implementation of each layer is expounded in detail,and reasoning method based on structure of maintainability information nodes is proposed,by learning organization and representation of maintainability design information in the support module.Finally,maintainability design support function of box part is realized,using VB and COM programming to build maintainability design support module based on CATIA.
