汽轮机叶片数学模型的建立与计算机辅助绘图方法的实现

The foundation of math model for steam turbine vane & realization with the CAD method

根据汽轮机叶片若干个不同部位截面的型线图,采用插值方法,建立整只叶片的数学模型,并利用计算机辅助设计(CAD)技术,计算和绘制叶片任意位置的型线图。从而为工程上研究、制造叶片模具提供一种高效、准确的方法。

Due to the section variety of steam turbine vane is series, warrants the chart of section type-line, using inserting value method strikes up the math model for steam turbine vane and utilizing the CAD method to account and the chart of section type-line.Offers the high efficiency and exact method for manufacture of steam turbine vane die.
