基于自定义特征的透平叶轮产品族参数化建模方法研究

Study on parametric modeling of turbo-expander wheel families based on UDF

针对制冷透平膨胀机叶轮的结构特点,以UG软件为支撑平台,运用实体建模概念,结合表达式、电子表格以及用户自定义特征等功能,提出了叶轮产品族三维参数化建模的方法,为企业实现叶轮产品的快速开发提供了一种新的途径。

By analyze the structure peculiarity of turbo-expander wheel, base on the software of UG, using the concept of solidmodeling, combine with the function of expressions, spreadsheet and user defined feature, present the ways of parametric modeling of turbo-expander wheel product families, give a new method to the quickly development of the turbo-expander wheel product.
