基于CATIA的发动机连杆参数化设计研究

Research on Parametric Design of Engine Connecting Rod Based on CATIA

文章介绍了基于CATIA的发动机连杆数模参数化设计方法。在已有三维数模的基础上,通过定义关键参数和方程式,完成了数模的参数化设计。后续可以直接修改关键参数值得到新的数模,减少修改和新建数模的时间,提升开发效率。

In this paper,the mathematical model parameterization method of engine connecting rod based on CATIA is introduced.On the basis of the existing 3D mathematical model,the parameterization of the mathematical model is completed by defining the key parameters and equations.Later,key parameter values can be directly modified to get a new digital model,which reduces the time of modification and new digital model and improves development efficiency.
