| 摘 要： | 针对传统的水泵CAD软件在绘制和调控展开流线时很大程度上依靠经验的判断,提出了用单段和多段三次样条曲线来模拟展开流线,以及约束调控样条曲线的数学模型。对多段三次样条曲线模拟展开流线给出了非常具体的绘图及调控方法,具有较强的工程实用价值。

| Abstract: | According to the condition that traditional method to draw and control the expanding streamlinemostly depending on the designers experience, the method to simulate the expanding streamline by single ormulti cube spline curves, and the mathematical model to control the spline curve are proposed. The approachof simulating and controlling the expanding streamline with multi cube spline curves is narrated in detail,which proved be practical. |
