摘要
本文从数学上证明了目前研制的转桨式水轮机数字协联装置所采用的三种数学模型是等价的,并提出了一种新数学模型。此模型运算简单,有一定的适应场合。若新模型与原模型结合应用,可提高整个曲面拟合的精度。
Three forms of mathematical models that adopted in the digital cam for Kaplan turbine are identical. The paper puts forward a new mathematical model which operates simply and is applicable under given eonditions. The new model can raise the precision of the surface filling with the original models.
