基于UG的飞机发动机叶片造型的方法研究

Modeling method of aero-engine based on UG

叶片是航空发动机的关键部件之一,针对其结构的复杂性和不规则性,介绍了基于UG的飞机发动机叶片造型方法。指出了造型过程中的难点和重点问题是:如何使叶片剖面对应的样条曲线经放样后成为光滑曲面,以及阻尼台的造型方法。以某飞机发动机叶片为例,对叶片造型中的几个问题进行分析,验证了其造型方法的可行性。结果表明:应用UG软件的曲面造型功能,使叶片的设计开发变得精确,进一步提高了叶片的设计效率和加工精度。

The difficult and key of the modeling is how to make the curves corresponding with blade sections into smooth camber and make the damp.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.The result is:the surface modeling of UG can make the development exactitude ,improve the design efficiency and manu...
