特征建模技术在产品设计中的应用

Research of the Feature Model and Application in the Product Design

针对ＣＡＤ技术中特征参数化问题，采用逐级分类的方法，给出了特征在产品设计领域的定义及其分类，对特征建模技术及处理方法进行了研究，同时采用面向对象技术对特征模型进行了描述，并结合加速度传感器的产品设计实例验证了基于特征的造型设计方法的可行性．

By the method of progressive classification, the definition in the classification of feature in the product design are given in the field of product design for the problem of feature-parameterization in CAD. And meanwhile, the technique of feature modeling is studied. The feature model is described by using the OOP. The design of acceleration sensor is used as an example to verify the feasibiligy of the implementation for the feature-based design.
