摘要
对双流道叶轮流道的结构特征进行了研究,讨论了双流道叶轮流道设计主要参数的确定方法,给出了一种新型流道中线的曲线方程,该曲线由部分渐开线和部分椭圆组成。分析了采用Pro/Engineer进行双流道叶轮流道三维建模的方法,发现直接的建模方法不易于实现,流道建模工作也比较难以进行。为此提出了采用Pro/Engineer二次开发的方法进行流道的三维参数化设计方法。研究了Pro/Engineer二次开发工具Pro/Toolkit的菜单设计技术、UI对话框技术及基于三维模型的参数化设计技术,着重研究了使用Pro/Engineer二次开发的方法进行双流道叶轮流道设计的一般流程,并给出了用Pro/Engineer二次开发方法进行双流道叶轮流道参数化设计的具体实例。
The channel structural feature of double channel er was studied. The method for obtai- ning the main parameters of the channel was discussed. A new curve equation of the channel was given, which was made of partial involute and partial ellipse. The 3D parameterized design of the channel based on Pro/Engineer second developing technology was presented. The technique for designing menu, UI dia- log boxes, and parameterized design technology based on three dimensional models were studied. General process of the design for double channel impeller based on Pro/Engineer second developing technology was specially studied. Finally, the specific example of 3D parameterized design of the channel was given.
