摘　　要：首先分析了离心式压气机工作轮的结构特点,指出随着新的排放标准的逐步实施,米勒定时和可变喷嘴等技术的应用已成为未来的发展方向,直纹曲面径向叶型在离心式压气机未来的发展中将有用武之地。进而针对直纹曲面径向叶型,给出了通过导线构造叶片曲面的造型方法。针对叶片的数控加工方法,提出利用非线性方程组的数值计算方法进行精铣叶片的刀具加工轨迹的求解方法。The paper analyzed the structural characteristics of the compressor working wheel.It is pointed out that with the gradual implementation of new emission standards,application of the technologies such as Miller timing and variable geometry nozzle has become the development direction,and so,the ruled surface radial leaf will have its uses in development of centrifugal air compressor.The paper gives the blade surface modeling method and the blade CNC machining method.
