摘要
本文介绍了基于三维机械设计软件——Solidworks2000的航空发动机叶片造型,指出了造型过程中的难点和重点问题是:如何使与叶片剖面对应的样条曲线经放样后成为光滑曲面。以某型发动机压气机叶片造型为例,利用所得造型计算了叶片的自振频率,计算结果表明:本文的造型方案可行,造型结果可靠、准确。
The modeling method of aero - engine blade from the solidworks is studied. The difficult and key point during the modeling is pointed out, that is, how to make the curves corresponding with blade sections into smooth camber. Some aero- engine blades are taken as examples, the intrinsic frequencies of the blades are calculated by the corresponding models. It is found that not only the modeling method is feasible but also the results based on the method are both reliable and precision.
