利用三维软件Pro/E中的参数化设计功能,基于参数和约束关系,建立了两个典型的离心风机形片与扭曲叶片的模型文件,同时利用二次开发工具VC++6.0建立风机叶片结构参数的动态MFC,通过Pro/E中自带的Protoolkit工具包的调用,实现了模型文件与动态MFC中风机叶片结构参数动态传递,极大简化了风机叶片建模的过程,提高了建模的效率。
Based on the parametric design functions in the three-dimensional software Pro / E, two typical model files of centrifugal fan blades and twisted blades are established based on the parameters and constraint relations. At the same time, the secondary development tools VC ++ 6.0 is used to establish the fan blade structure Parameters of dynamic MFC, through Pro / E comes Protoolkit toolkit calls to achieve the dynamic transfer of model files and dynamic MFC fan blade structure parameters, greatly simplifying the fan blade modeling process and improve the modeling effectiveness.
