| 摘 要： | 采用Hermite参数曲线构造水泵叶型的流线展开线，借助自由曲面造型技术，提出了在屏幕上动态调控叶片曲面的方法。此方法直观而灵活，非常适合于CAD系统，不仅能如实地在计算机上再现手工设计中广泛使用的方格网保角变换法叶片绘型过程，而且可直接得到叶片的三维曲面造型结果。

| Abstract: | Hermite curve is adopted for constructing the stream-line on pump blade. A new method to control the blade shape dynamically on computer screen is proposed. The blade shape designed by this method is met the needs of blade angle and include angle for any stream-line effectively. This is very useful for CAD system. It make the blade drawing process known as Equal-angle Conversion method that used in manual style widely possable in CAD software. An example for the application of this method has been given. |
