摘　　要：提出了一套针对插装阀集成块CAD的特征定义和分类方法,描述了插装阀集成块的所有特征信息及各类特征之间的关系,建立了插装阀集成块CAD的特征信息模型,应用面向对象的技术实现了集成块特征信息模型的计算机描述,并设计了基于该模型的插装阀集成块CAD系统的总体结构。最后,通过工程实例,验证了基于特征的插装阀集成块实体造型方法的有效性和系统的可行性。A method of definition and classification of feature for CAD of cartridge valve blocks was introduced. Based on the method, the feature of cartridge valve blocks and the relation among the feature was described, and a product model based on feature was built. An object-oriented description of the model was presented in computer language. The framework of CAD system for cartridge valve blocks was designed based on the model. An example was given to testify the effectiveness and feasibility of the method.
