摘要
针对目前机械零件大多是基于二维、面向工程图、静态的建库方法 ,提出了一种基于特征的动态图库研究方法。系统地介绍了建立图库特征的定义及其包含的信息 ;采用面向对象的技术方法建立了闸阀图库 ,库中零件为参数驱动的概念模式 ,可由系列化的尺寸参数驱动产生具体图形 ,从而实现图库的动态化、开放性 ;最后给出了图库中阀杆的实现过程。
Based on a graphing method for creating a 2D,engineering graph oriented and static database for designing mechanical parts (such as gate vales), a method for researching the character based dynamic graphing database is described The database definition and information are also presented The object oriented technique is applied to build a database for gate valves,where the conceptual mode for parts is of parameter driving The specific graph is created by using serial dimension parameter driving to database dynamic and open Finally, graphing process for valve stem is demonstrated in the database
