为了提高涡轮冷却叶片的结构设计效率，采用UG OPEN API与特征参数相结合的方法，建立涡轮叶片典型冷却结构的参数化设计模型。通过定义壁厚、隔板特征参数实现内外型的参数化设计，基于此模型，通过定义气膜孔、扰流肋、劈缝、扰流柱、旋流冷却结构的特征参数进行编程输出特征形状的点坐标和方向等参数。通过UG OPEN API实现特征结构的快速三维建模。设计人员通过参数修改，即可快速地进行三维建模，提高了设计效率，大大缩短了结构设计周期。
In order to improve the structural design efficiency of turbine cooling blades, a parameterized design technique for typical cooling structures of turbine blades was established by combining UG OPEN API with characteristic parameters. By defining the wall thickness and partition characteristic parameters, the parameterized design of the inner and outer shapes was achieved. Based on this model, the point coordinates and directions of the characteristic shapes were programmed and output by defining the characteristic parameters of the film cooling holes, ribs, trailing edge slot, pin-fin, and vortex cooling structures. Rapid 3D modeling of feature structure was realized by UG OPEN API. Designers can quickly perform 3D modeling by modifying parameters, improving design efficiency and greatly shortening the structural design cycle.
