复杂机械产品 CAD 系统开发中面向对象的模型分析

The object oriented model analysis in the development of complex mechanical product CAD system

本文针对复杂机械产品ＣＡＤ系统的特点，讨论了采用面向对象技术建立系统模型的有效方法以及模型表达完备性、适定性、非冗余性和一致性四条原则，并介绍了以上方法和原则在门座起重机ＣＡＤ系统模型分析中的应用。

Aimed at the characteristics of complex mechanical product CAD system this paper discussed an effective method for establishing system model by adopting the object oriented technique and the four principles of integrity,suitability,non redundancy and consistency for model expression,and also introduced the application of the above method and principles in the model analysis on the CAD system of portal crane.
